Description

Technical Field

[0001] The invention relates to the technical field of lasers, and in particular provides a solar-pumped and driven laser system. Background Art

[0002] Solid-state lasers are currently the most widely used and most technologically mature type of lasers. Their principle is to achieve laser power amplification under pumping conditions based on stimulated emission of light. Its basic structure is to excite the gain medium in the laser resonant cavity through a pump source, and the stimulated emission light generated is continuously amplified through the resonant cavity and finally output as a laser. Conventional laser pump sources generally convert electrical energy into light energy of a specific wavelength, and then use this light energy to stimulate the generation of lasers. This method involves multiple energy conversion processes, and the energy conversion efficiency is extremely low. Most of the energy is converted into reactive power and dissipated. Sunlight has an extremely wide spectral range, which includes a spectrum that can be used as a laser pump light source. Therefore, sunlight can be directly used as a pump light source for lasers, without the need for multiple energy conversions, which is convenient for realizing and expanding the application scope of laser technology, and has objective prospects and economic value.

[0003] The current environmental problems and energy crisis have gradually emerged, and research on how to utilize clean renewable resources such as solar energy has received increasing attention. Traditional solar energy collection methods mainly include photothermal conversion, photovoltaic conversion, and solar-hydrogen energy conversion. Among them, solar cell technology is a relatively mature technology with relatively high energy utilization rate.

[0004] The general idea of ​​the existing technology of pumping laser with solar energy is to concentrate the sunlight through a lens to increase its energy density, and inject the concentrated light spot from the side or end face of the gain medium as a pump light source. In order to collect more solar energy, the focusing mirror will be very large. It is difficult to process large-size lenses made of conventional materials, which is costly and easy to damage. Therefore, Fresnel lenses are often used. The focusing spot of the sunlight injection point on the laser gain medium is generally the focus of the focusing lens. The concentrated light spot is an extremely fine circle. The power density of the focusing point is high, and it is easy to accumulate heat when working for a long time, resulting in various thermal effects that are unfavorable to the gain medium. In addition, in order to improve the utilization rate of sunlight, a set of reflective converging lenses will be designed on the back of the gain medium to reflect and converge the sunlight and pass it through the gain medium again. However, this lens is generally an elliptical or parabolic mirror, which is difficult to process. After the sunlight passes through the gain medium once, the band that can be used as pump light has been absorbed. Even if the emitted sunlight is reflected back to the gain medium, the remaining sunlight band components have almost no utilization value for the gain medium. Therefore, when using sunlight to stimulate the generation of lasers, only a very small part of the spectral energy in the sunlight spectrum is actually utilized, and the light energy utilization rate is still relatively low. Summary of the invention

[0005] The technical task of the present invention is to provide a solar-pumped and driven laser system to solve the above problems.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A solar-powered and driven laser system, the laser system comprising an optical lens group and a solar cell multiplexing system, and a laser array system; the optical lens group and the solar cell multiplexing system are composed of a plurality of splicing parts with multiplexing functions, which can be spliced ​​into a convergent lens array or a reflector array, or spliced ​​into a solar cell panel array; the structure of the laser array system comprises a gain medium array, a transparent substrate, the gain medium array is distributed on the transparent substrate, and the gain medium array and the grating, coating or reflector at its end constitute a laser resonant cavity array. The laser resonant cavity can be formed by arranging corresponding total reflection mirrors and semi-reflection mirrors at both ends of each gain medium, or by coating a total reflection film and a semi-reflection film at both ends of each gain medium, or by photolithography of gratings with different reflectivity at both ends of each gain medium.

[0008] The lens composed of multiple converging lens groups converges sunlight onto the gain medium array of the laser array system. The gain medium absorbs specific spectrum in sunlight and generates laser. After being absorbed by the multi-layer gain medium array, the remaining unabsorbed sunlight passes through the laser array system and shines on the solar panel array composed of multiple solar cells. It is converted into electrical energy for storage and provides energy for the sunlight positioning and tracking system, control and power system, and additional laser pumping in the laser array system.

[0009] The gain medium array adopts a structure that is beneficial to reducing the laser threshold, including but not limited to a thin film waveguide structure, a slab structure, a rod structure, a microchip structure, and an optical fiber structure. The length of the pump light receiving surface of the gain medium is greater than its thickness, so as to eliminate the diffraction phenomenon of the laser during internal reflection.

[0010] The two end faces of each gain medium in the gain medium array are parallel planes or curved structures with the normal direction being the same as the light transmission direction;

[0011] Or, two end faces of each gain medium in the gain medium array are at a certain angle to form a Brewster window structure;

[0012] Alternatively, one end face of each gain medium in the gain medium array is a necked structure, and the shape and size of the necked end are compatible with the size of the optical fiber.

[0013] Alternatively, multiple gain media in the gain medium array are connected in series to form a laser resonant cavity, for example, by setting a Paul prism, setting two 45° reflectors, using optical fiber transmission, or aligning and directly connecting gain media located at corresponding positions on different transparent substrates.

[0014] The transparent substrate is in the shape of a flat plate, a curved plate, a solid cylindrical shape, a solid elliptical cylindrical shape, a cubic cylindrical shape or a parallelogram cylindrical shape, a prism shape, a solid truncated cone shape, a hollow or solid polygonal cone shape, or a combination or array of multiple shapes of the same or different shapes.

[0015] The transparent substrate is made of a material with a wide spectral transmittance range, high thermal conductivity, and low thermal expansion coefficient, including but not limited to optical grade quartz glass, lithium niobate crystal, YAG, sapphire, etc., and the number is one or more arranged in an array.

[0016] The laser resonant cavity array is staggeredly distributed on the upper and lower surfaces or the inner and outer surfaces of the transparent substrate in a fence manner, and different three-dimensional array structures are formed according to different shapes and array modes of the transparent substrate to increase the sunlight irradiation area and reduce the negative impact of thermal effects on the laser when the gain medium volume is large.

[0017] The splicing part includes an optical mirror group surface and an opposite surface, a solar cell integrated board surface and an opposite surface and two end surfaces, wherein the two end surfaces are respectively connected to two retractable support rods through a rotating shaft, so that the splicing part can rotate around the axis; the optical mirror group surface and its opposite surface constitute a converging lens, which converges sunlight to a gain medium array, and two adjacent opposite surfaces are double-sided solar cell integrated board surfaces or one side is a solar cell integrated board surface and the other side is a sunlight reflector.

[0018] The optical mirror surface and the opposite surface of each splicing part are long strip lenses spliced ​​together by multiple converging lenses, which converge sunlight into long strip-shaped light spots and irradiate them onto the gain medium array of the laser array system. The shape and size of the light spot can cover all gain medium arrays.

[0019] The telescopic support rod is installed on the circular track and can move along the track. By adjusting the length of the telescopic support rod and cooperating with the circular track, multiple splicing parts can be spliced ​​into a circular mirror, an elliptical mirror, a parabolic mirror or other required shapes.

[0020] The transparent substrate is a hollow column type, and all laser resonant cavity arrays on the transparent substrate share a set of total reflection mirrors, half reflection mirrors and focusing mirrors.

[0021] The total reflection mirror, the half reflection mirror and the focusing mirror are annular lenses with hollowed-out middle parts.

[0022] The transparent substrate is a hollow truncated cone or a plurality of coaxially connected hollow truncated cones with different convergence angles. The light convergence focal points of the laser resonant cavity arrays on the truncated cones overlap to achieve a self-focusing function.

[0023] The laser output by the laser resonant cavity array can also be used as a pump light source for co-band pumping and injected into another gain medium to obtain a higher quality laser output.

[0024] The laser system also includes a sunlight positioning and tracking system, a control and power system, a laser beam combining unit, and an additional laser pump.

[0025] The solar panel array can provide power for additional laser pumping and provide additional pump light for the laser resonator array, further increasing the laser output power.

[0026] Compared with the prior art, the solar-pumped and driven laser system of the present invention has the following outstanding beneficial effects:

[0027] The present invention uses a micro laser resonant cavity structure to reduce the laser threshold, so that lasers can still be generated when the energy of the pumping sunlight is low. The gain medium array structure is conducive to heat dissipation, which can effectively reduce the impact of various thermal effects on the laser, and at the same time facilitate the acquisition of laser output with greater energy. The use of solar cells replaces the method of using reflectors to reflect and focus solar energy back to the gain medium in many existing solutions, because the spectrum that contributes to the generation of lasers has been completely absorbed in the sunlight that passes through the laser gain medium, and even if it is reflected back, the effect is not great. Fig.17 and Fig.18 Analysis shows that the wavelengths of sunlight that can be absorbed by the gain medium for laser generation are only a few absorption peaks within the range of 350nm to 400nm, 500nm to 600nm, and 700nm to 900nm. Most of the sunlight energy is still not effectively utilized. This solution uses solar cells instead of reflectors. Solar cells have a very wide absorption range for the solar spectrum, and can also utilize the spectral range in sunlight that does not contribute to the generation of lasers and convert it into electrical energy, which is a real way to greatly improve the utilization rate of sunlight. The electrical energy generated can be used to supply the entire system. The excess electrical energy can also drive additional laser pumps to provide additional pumping light for the laser resonant cavity array, thereby further increasing the laser output power. This system can operate independently in the outer space environment without the need to draw electricity from artificial satellites or space stations. It is also compatible with the ground use environment and has the technical prospect of obtaining high-power lasers. It has broad application prospects in the fields of space laser communications, laser radar, atmospheric and surface structure detection, laser navigation, laser weapons, and laser remote power transmission.

[0048] Example 1

[0049] like Figure 1 As shown, a solar-pumped and driven laser system includes an optical lens group and solar cell multiplexing system 1, a laser array system 2, a sunlight positioning and tracking system 3, a control and power system 4; a laser beam combining unit, and an additional laser pump; the additional laser pump is used to convert the excess electricity collected by the solar cell into pump light, providing an additional pump source for the laser resonant cavity array, thereby further improving the power of the output laser.

[0050] like Figure 2 As shown, the optical lens group and solar cell multiplexing system 1 is composed of a plurality of splicing parts 1-1 with multiplexing functions, which can be spliced ​​into a focusing lens array or a reflector array, and can also be spliced ​​into a solar cell panel array;

[0051] like Figure 2 , Figure 3 As shown, the splicing part 1-1 includes an optical mirror group surface 1-1-2 and an opposite surface, a solar cell integrated panel surface 1-1-3 and an opposite surface and two end surfaces, wherein the two end surfaces are respectively connected to two retractable support rods 1-1-5 through a rotating shaft 1-1-6, so that the splicing part 1-1 can rotate around the axis; the optical mirror group surface 1-1-2 and its opposite surface constitute a converging lens to converge sunlight to a gain medium array, and two adjacent opposite surfaces are a double-sided solar cell integrated panel surface 1-1-3 or one side is a solar cell integrated panel surface 1-1-3 and the other side is a sunlight reflector; by rotating the cuboid to make different sides face the sun, the converging lens, solar cell or light reflector functions can be switched.

[0052] The retractable support rod 1-1-5 is installed on the circular track and can move along the track. By adjusting the length of the retractable support rod 1-1-5 and cooperating with the circular track, multiple splicing parts can be spliced ​​into a circular mirror, an elliptical mirror, a parabolic mirror or other required shapes.

[0053] The control and power system 4 can intelligently adjust the number of splicing parts 1-1 serving as optical lens groups and the number of splicing parts 1-1 serving as solar cells according to the data measured by the sunlight positioning and tracking system 3, and control the movement of each splicing part on the circular track 1-2 so that the system always obtains the best sunlight incident angle.

[0054] The laser array system 2 is composed of a gain medium array 2-1, a laser resonant cavity array 2-2, a transparent substrate 2-3, a laser beam combining unit 2-4, and an additional laser pump. The gain medium array is distributed on a transparent substrate 2-3 made of a special material with a wide spectral transmission range.

[0055] like Figure 4 As shown, the gain medium 2-1 adopts a structure that is beneficial to lowering the laser threshold, including but not limited to a thin film waveguide structure, a slab structure, a rod structure, a microchip structure, and an optical fiber structure, such as Fig. 9 As shown; this embodiment uses a slat structure.

[0056] The gain medium 2-1 can be any known material that can generate laser light, including but not limited to yttrium aluminum garnet series doping compounds (such as Nd:YAG, Yb:YAG, Ho:YAG, Er:YAG, Cr:Nd:YAG); yttrium vanadate series doping compounds (such as Nd:YVO 4 ); Ruby (Cr 3+ :Al 2 O 3 ), sapphire (Ti 3+ :Al 2 O 3 ), Emerald (Cr 3+ :Be 3 Al 2 (SiO 3 ) 6 ), Alexandrite (Cr 3+ :BeAl 2 O 4 ), Nd 3+ :GGG(Gd 3 Ga 5 O 12 ), Cr 3+ :ScBO 3 ,Co 2+ :MgF 2; or an optical fiber or a photonic crystal fiber doped with a transition metal element or an ion of the transition metal element; considering the requirement of the space laser to resist cosmic radiation, preferably, this embodiment uses Cr:Nd:YAG as the gain medium.

[0057] The laser resonant cavity array 2-2 is distributed on a transparent substrate 2-3, and the resonant cavity includes a gain medium 2-1, a total reflection mirror 2-2-1, and a half reflection mirror 2-2-2, wherein the total reflection mirror and the half reflection mirror can be a plane mirror, a convex mirror, a concave mirror, or a conical mirror, respectively; the total reflection mirror 2-2-1 and the half reflection mirror 2-2-2 can be replaced by a total reflection film 2-2-3 and a half reflection film 2-2-4 respectively coated on the two light-passing surfaces of the gain medium. In this embodiment, the total reflection film 2-2-3 and the half reflection film 2-2-4 are selected.

[0058] The length of the pump light receiving surface of the gain medium 2 - 1 is greater than its thickness so as to eliminate the diffraction phenomenon of the laser during internal reflection.

[0059] like Figure 8 As shown, the laser resonant cavity array 2-2 is staggeredly distributed on the upper and lower surfaces of the transparent substrate 2-3 in a fence manner to increase the sunlight irradiation area and reduce the negative impact of deformation, stress, thermal lens effect, etc. caused by thermal effects when the gain medium volume is large on the laser.

[0060] The material of the transparent substrate 2-3 is selected from a material with a wide spectral transmittance range, high thermal conductivity and small thermal expansion coefficient. Preferably, quartz material is selected in this embodiment.

[0061] This embodiment provides a space laser system that does not require additional power supply and can automatically track the sun's position and adjust the system's light acceptance angle. It uses a micro-laser resonant cavity array structure to reduce the laser oscillation threshold, making it easier to obtain high-power laser output and effectively reduce the negative impact of thermal effects on the laser. The combination of a solar-pumped laser and a solar cell greatly improves the utilization rate of sunlight energy.

[0062] Example 2

[0063] like Figure 5 As shown, on the basis of Example 1, the two optical surfaces of the gain medium 2-1 are made into a Brewster window 2-1-1 structure, and accordingly, the laser beam combining unit 2-4 uses polarization-maintaining optical fiber and a polarization combiner to obtain a linearly polarized output laser.

[0064] or, as Figure 6 , Fig. 9As shown, as shown, based on Example 1, by setting a Paul prism 2-2-5 between two adjacent gain media 2-1, multiple gain media can be connected in series, the laser power of a single laser resonant cavity can be increased, and the number of optical fibers in the laser beam combining unit 2-4 can be reduced.

[0065] Example 3

[0066] like Figure 7 As shown, on the basis of Example 1, the gain medium adopts a thin film waveguide structure, and gratings with different reflectivity are respectively etched at both ends of each gain medium to replace the full-reflection mirror and the half-reflection mirror; the laser resonant cavity includes a laser gain medium 7-1, a high-reflection grating 7-2, a low-reflection grating 7-3, and a trapezoidal waveguide structure 7-4;

[0067] The trapezoidal waveguide structure 7-4 is located at the output end of the laser resonant cavity. This structure can reduce the size of the waveguide output end to match the optical fiber, and can be directly connected to the optical fiber by fusion splicing, so as to directly guide the laser into the optical fiber and eliminate the need for an optical fiber coupling mirror set.

[0068] The high reflection grating 7-2 and the low reflection grating 7-3 are a grating pair with matching central wavelengths and are directly engraved in the thin film waveguide.

[0069] Furthermore, based on the inspiration from the above structure, a single-clad or unclad gain fiber can be directly used as a gain medium array, and a high-reflection grating and a low-reflection grating can be photolithographically formed at both ends to form a laser resonant cavity.

[0070] Example 4

[0071] like Fig.10 , Fig.11 As shown, relative to Example 3, the laser resonant cavity array 10-1 and the transparent substrate 10-2 are hollow cylindrical structures, and the resonant cavity arrays located inside and outside the transparent substrate 10-2 are staggered structures;

[0072] The advantage of this structure is that all laser resonant cavities in the array can share a set of total reflection mirrors 10-3, half reflection mirrors 10-4, and focusing mirrors 10-5, without having to process a set of very small mirror groups for each laser resonant cavity, thus greatly reducing the difficulty of processing optical accessories, and this structure is also applicable to flat-plate arrays;

[0073] The multiple laser beams focused by this structure can be injected into a longer section of optical fiber for beam shaping to obtain a uniform light spot.

[0074] like Fig.12 As shown, further, the shared reflector 10-6, the semi-reflector 10-7, and the focusing mirror 10-8 are annular lenses, and the cut-off portion of each lens can be processed into other lenses for use, which greatly saves lens materials;

[0075] The multiple laser beams focused by this structure can be injected into a longer section of optical fiber for beam shaping to obtain a uniform light spot.

[0076] like Fig.13 As shown, further, this embodiment can also use a fiber bundle combination method.

[0077] like Fig.16 As shown, the laser beam combining unit 2-4 can be directly used or injected into the optical fiber after being converged and shaped by an optical lens group, or it can be coupled into a fiber combiner after each laser resonant cavity is coupled; this embodiment uses a fiber beam combining method, and it should be understood that when there are many optical fibers that need to be combined, the laser beam combining unit 2-4 can be composed of a plurality of fiber combiners.

[0078] Different optical devices can be added to the laser beam combining units 2-4 to achieve power beam combining, coherent beam combining, spectrum beam combining, or even to inject the laser generated by the laser array system as a same-band pump light source into a new gain medium to obtain a higher quality laser output.

[0079] Example 5

[0080] like Fig.14 As shown, relative to Example 4, the laser resonant cavity array 14-1 and the transparent substrate 14-2 are hollow truncated cone structures, and the resonant cavity arrays located inside and outside the transparent substrate 14-2 are staggered structures;

[0081] The advantage of this structure is that the laser beams output by all the laser resonators in the array will intersect at one point, that is, it has a self-focusing function, so a set of focusing mirrors can be omitted;

[0082] The multiple laser beams focused by this structure can be injected into a longer section of optical fiber for beam shaping to obtain a uniform light spot.

[0083] like Fig.15 As shown, further, by coaxially connecting multiple hollow truncated cones with different convergence angles in series and making the array focusing points of each truncated cone overlap, higher laser power can be obtained;

[0084] The multiple laser beams focused by this structure can be injected into a longer section of optical fiber for beam shaping to obtain a uniform light spot.

[0085] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
