Description

Technical Field

[0002] As lasers gradually enter the public eye, their miniaturization and environmental adaptability have become critical issues that urgently need to be addressed. Today, lasers need to operate normally under increasingly harsh environmental conditions, such as maintaining stable operation within a temperature range of -20℃ to 85℃. Lasers are typically assembled from multiple different components, including pump sources, gain media, and various lenses. During assembly, whether using adhesives with different properties for fixing or screws for tightening, it is difficult to avoid the deformation of adhesives or materials caused by temperature changes. This deformation can lead to displacement deviations between components, and in severe cases, it can cause the laser to malfunction or even fail. Current technologies do not include testing for lasers under different temperature environments, resulting in reduced reliability. Utility Model Content

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] Currently, lasers operate in complex and variable environments, with temperature variations having a significant impact on their performance. Existing technologies do not conduct performance tests on lasers under different temperature conditions, resulting in poor temperature adaptability and low operational reliability.

[0036] In view of this, the designers have provided a laser performance testing system that can test the changes in energy and beam divergence angle of a laser at different temperatures, and improve the laser based on the test results, thereby improving the reliability and stability of laser operation.

[0037] Please combine Figures 1-6 In this embodiment, the laser performance testing system includes a temperature control device 100, an optical path transmission device 200, and a beam receiving device 300. The temperature control device 100 includes a carrier 110, a heating mechanism 120, a focusing lens 130, and an energy meter 140. The carrier 110 is used to position the laser body 001 under test. Both the carrier 110 and the beam receiving device 300 are mounted on the optical path transmission device 200. The heating mechanism 120, the focusing lens 130, and the energy meter 140 are all mounted on the carrier 110. The heating mechanism 120 is used to adjust the temperature of the laser body 001 under test. One of the focusing lens 130 and the energy meter 140 is used, such that one of them is located on the beam propagation path of the laser body 001 under test. The optical path transmission device 200 is used to adjust the beam emitted by the laser body 001 under test and passing through the focusing lens 130, so that the beam is focused onto the beam receiving device 300.

[0038] As described above, the laser performance testing system provided in this embodiment operates as follows:

[0039] When energy testing is required, the position of the energy meter 140 is adjusted so that it is positioned in the beam propagation path of the laser under test (SUT) 001. Then, the SUT 001, located on the carrier 110, is activated, causing its emitted beam to be directed towards the energy meter 140. The energy meter 140 then acquires the energy information of the SUT 001 in real time. During the test, the temperature of the SUT 001 can be adjusted by regulating the operating state of the heating mechanism 120, thereby allowing the acquisition of energy changes in the SUT 001 under different temperature conditions.

[0040] When beam divergence testing is required, the position of the focusing lens 130 is adjusted so that it is positioned on the beam propagation path of the laser under test (SUT) body 001. Then, the SUT body 001, located on the carrier 110, is activated, causing its emitted beam to be directed towards the focusing lens 130. The propagation direction is adjusted by the optical path transmission device 200, ensuring the beam ultimately reaches the beam spot receiving device 300. The beam divergence angle information of the SUT body 001 is acquired in real time through the beam spot receiving device 300. Similarly, during the test, the temperature of the SUT body 001 can be adjusted by regulating the operating state of the heating mechanism 120, thereby allowing the acquisition of changes in the beam divergence angle of the SUT body 001 under different temperature conditions.

[0041] In this way, through the cooperation of the temperature control device 100, the optical path transmission device 200, and the light spot receiving device 300, the performance of the laser body 001 under test can be tested. During the test, the working state of the heating mechanism 120 of the temperature control device 100 can be adjusted as needed, thereby adjusting the temperature environment of the laser body 001 under test, obtaining the changes in energy and beam divergence angle of the laser body 001 under different temperature environments, and guiding the improvement of the laser body based on the obtained test results, thereby obtaining a laser with stable performance and strong environmental adaptability, greatly expanding the application area of ​​the laser.

[0042] The following embodiments illustrate the details of the laser performance testing system of the application by way of example.

[0043] Please combine Figure 1 In this embodiment, optionally, the laser performance testing system includes a temperature control device 100, an optical path transmission device 200, and a light spot receiving device 300.

[0044] Please combine Figure 1 , Figures 4-6The temperature control device 100 includes a carrier 110, a heating mechanism 120, a focusing lens 130, an energy meter 140, a driver 150, a first temperature sensor 160, and a second temperature sensor 170. The carrier 110 is used to position the laser body 001 under test. The heating mechanism 120, focusing lens 130, energy meter 140, driver 150, first temperature sensor 160, and second temperature sensor 170 are all mounted on the carrier 110. The heating mechanism 120 is used to regulate the temperature of the laser body 001 under test. The driver 150 is connected to both the focusing lens 130 and the energy meter 140, adjusting their positions relative to the laser body 001 so that one of them is used, placing it in the beam propagation path of the laser body 001. The first temperature sensor 160 and the second temperature sensor 170 are both communicatively connected to the heating mechanism 120. The first temperature sensor 160 is used to acquire the temperature of the laser body 001 under test, and the second temperature sensor 170 is used to acquire the temperature of the area between the laser body 001 under test and the heating mechanism 120. By cooperating with the first temperature sensor 160 and the second temperature sensor 170, the working state of the heating mechanism 120 can be better controlled.

[0045] Optionally, the carrier 110 includes a mounting base 111, a heat insulation cover 112, and heat dissipation fins 113. The heat insulation cover 112 and the mounting base 111 are connected, and together they define a heat insulation cavity 114. The laser body 001 under test is located inside the heat insulation cavity 114. The heat inside the heat insulation cavity 114 is not easily dissipated, and the temperature inside the heat insulation cavity 114 is basically the same, ensuring that all positions of the laser body 001 under test are basically under the same temperature state, thereby improving the accuracy of the test results. The heat dissipation fins 113 are mounted on the mounting base 111 and can dissipate heat from the heating mechanism 120, preventing the heating mechanism 120 from overheating and affecting its service life.

[0046] Specifically, the mounting base 111 is roughly a rectangular block, having opposing first and second sides, opposing third and fourth sides, and opposing top and bottom surfaces. The first side has outwardly folded edges 1111 on both sides corresponding to the third and fourth sides, with multiple first fixing holes 1112 arranged sequentially at intervals along the top and bottom surfaces. The second side has a slot into which the heating mechanism 120 engages. The heating mechanism 120 can be inserted into or pulled out of the slot for easy assembly and disassembly. A portion of the top surface is designated as a positioning plane for fixing the laser body 001 under test. A mounting groove 1113 is provided within the area enclosed by the edge of the positioning plane. The mounting groove 1113 can be rectangular, and a second temperature sensor 170 is installed within it. After the laser under test body 001 is installed on the positioning plane using bolts or other fasteners, the laser under test body 001 closes the opening of the mounting groove 1113, so that the second temperature sensor 170 does not directly obtain the temperature inside the insulation cavity 114, but instead obtains the temperature between the laser under test body 001 and the heating mechanism 120. At the same time, a receiving groove 1114 is also provided outside the area on the top surface located on the positioning plane. The receiving groove 1114 can be recessed, and the driver 150 is installed in the receiving groove 1114, making reasonable use of the internal space of the fixing base 111, improving the compactness of the overall structure, and reducing the overall volume.

[0047] During assembly, the first side is attached to the optical path transmission device 200. Bolts or other fasteners can be inserted into the first fixing hole 1112 to fix the fixing seat 111 to the optical path transmission device 200. The second side is away from the optical path transmission device 200. The heating mechanism 120 is inserted into the slot from the second side for easy installation. There can be two heat dissipation fins 113, which are respectively installed on the third and fourth sides. This can effectively reduce the heat of the heating mechanism 120 itself and prevent the heating mechanism 120 from overheating and affecting its service life.

[0048] Please combine Figures 4-6Optionally, the insulation cover 112 is configured as a rectangular shell with one open side. The insulation cover 112 has opposing inner and outer surfaces. It has a light-transmitting hole 1121 and a wire-passing hole 1122. The light-transmitting hole 1121 allows a light beam to pass through, and the wire-passing hole 1122 allows a wire bundle from the laser body 001 under test to pass through. The wire bundle and the wire-passing hole 1122 are interference-fitted, and the wire-passing hole 1122 has a good sealing effect. Specifically, the light-transmitting hole 1121 extends through both the inner and outer surfaces; that is, one end of the light-transmitting hole 1121 is located on the inner surface, and the other end is located on the outer surface. The light-transmitting hole 1121 can be a circular hole. The open side of the insulation cover 112 is connected to the top surface of the mounting base 111, and the top surface closes the open side of the insulation cover 112. The two work together to define the insulation cavity 114. The laser body 001 under test is installed inside the insulation cavity 114. The first temperature sensor 160 is installed inside the insulation cover 112. The first temperature sensor 160 can obtain the temperature inside the insulation cavity 114, thereby obtaining the temperature of the laser body 001 under test. Furthermore, after the laser body 001 under test is installed in the insulation cavity 114, the front side with the beam emitting end of the laser body 001 under test can be in contact with the inner side, and the beam can pass through the light transmission hole 1121. In this way, the insulation cavity 114 is not easily connected to the external environment at the light transmission hole 1121. The insulation cavity 114 has high airtightness, which makes it easy to adjust the temperature of the insulation cavity 114 and ensures high temperature uniformity of the insulation cavity 114, making the temperature of the laser body 001 under test more uniform.

[0049] Due to the coordinated design of the first temperature sensor 160 and the second temperature sensor 170, the working state of the heating mechanism 120 can be reasonably controlled. Specifically, when the temperature difference between the first temperature sensor 160 and the second temperature sensor 170 is within 1°C, it indicates that the insulation cover 112 and the fixing base 111 are well fitted. This temperature difference information is transmitted to the heating mechanism 120, and the heating mechanism 120 can perform heating operations normally. In this state, the insulation cavity 114 has good sealing performance, and the laser body 001 under test located in the insulation cavity 114 is heated evenly. When the temperature difference between the first temperature sensor 160 and the second temperature sensor 170 is greater than 1°C, it indicates that the insulation cover 112 is not properly fitted with the fixing base 111 or there is a leakage area between the insulation cover 112 and the fixing base 111. This temperature difference information is transmitted to the heating mechanism 120, and the heating mechanism 120 stops operating, preventing overheating or energy waste. For example, when the insulation cover 112 is removed from the mounting base 111, the laser body 001 under test is exposed to the external environment, resulting in uneven heating and making it difficult to obtain good test results. Therefore, the heating mechanism 120 can stop operating to save energy. Alternatively, in some operations, the laser body 001 under test is not installed in the insulation cavity 114. In this case, the light transmission hole 1121 is opened, connecting the insulation cavity 114 to the outside. During the operation of the heating mechanism 120, if the temperature difference between the first temperature sensor 160 and the second temperature sensor 170 is greater than 1°, the heating mechanism 120 can also stop operating to prompt the operator to check the system status.

[0050] It should be understood that the first temperature sensor 160 and the second temperature sensor 170 can also be configured as thermistors, etc. The first temperature sensor 160 and the second temperature sensor 170 can communicate with the heating mechanism 120 via Bluetooth modules, etc.

[0051] Please combine Figures 3-6 Optionally, the driver 150 includes a linear telescopic mechanism 151 and a mounting platform 152. The linear telescopic mechanism 151 is installed within the receiving groove 1114, and the mounting platform 152 is connected to the telescopic end of the linear telescopic mechanism 151. The focusing lens 130 and the energy meter 140 are both mounted on the mounting platform 152, and are spaced apart in the telescopic direction of the linear telescopic mechanism 151. For example, the energy meter 140 is located on the side of the focusing lens 130 near the bottom of the receiving groove 1114. During operation, the linear telescopic mechanism 151 drives the mounting platform 152 to reciprocate linearly in the depth direction of the receiving groove 1114, thereby causing a change in the height of the focusing lens 130 and the energy meter 140, so that one of them is located on the beam propagation path of the laser body 001 under test.

[0052] It should be understood that the linear telescopic mechanism 151 can be configured as a cylinder, hydraulic cylinder, or electric push rod, etc.

[0053] In this embodiment, optionally, the optical path transmission device 200 includes a housing 210 and a reflector assembly. The reflector assembly is detachably mounted on the housing 210 and is used to adjust the propagation path of the beam from the laser body 001 under test so that the beam is focused onto the spot receiving device 300.

[0054] Please combine Figures 1-3 Optionally, the housing 210 has an internal optical path propagation channel. The housing 210 has a first side and a second side in its width direction, both of which are open. The first side has multiple second fixing holes 211, and the second side has multiple snap-fit ​​holes 212. A mounting base 111 is installed on the first side. The mounting base 111 can be aligned with the corresponding second fixing holes 211 as needed, and then bolts are used to lock the mounting base 111 to the housing 210, thus adjusting the height of the mounting base 111. This allows the beams from different types of laser bodies 001 under test to be emitted to the designated positions on the reflector group, providing flexibility. A beam receiving device 300 is installed on the second side. The beam from the laser body 001 under test can be directed from the first side to the reflector group, then exit from the second side and strike the beam receiving device 300.

[0055] Optionally, the reflector assembly includes a first reflecting unit 220, a second reflecting unit 230, and a movable reflector body 240. The first reflecting unit 220 includes a first mounting box 221 and multiple first fixed reflector bodies 222, all of which are mounted within the first mounting box 221. Each first fixed reflector body 222 forms a 45° angle with the horizontal plane, and adjacent first fixed reflector bodies 222 are symmetrically arranged. The first mounting box 221 is detachably connected to the outer casing 210, allowing multiple first fixed reflector bodies 222 to be simultaneously removed from the outer casing 210 for easy replacement. The second reflecting unit 230 includes a second mounting box 231 and multiple second fixed reflector bodies 232, all of which are mounted within the second mounting box 231. Each second fixed reflector body 232 forms a 45° angle with the horizontal plane, and adjacent second fixed reflector bodies 232 are symmetrically arranged. The second mounting box 231 is detachably connected to the outer casing 210 and is arranged at intervals relative to the first mounting box 221. Multiple second fixed reflector bodies 232 are mounted in the second mounting box 231, allowing for simultaneous removal of multiple second fixed reflector bodies 232 from the outer casing 210 for easy replacement. The movable reflector body 240 is connected to the beam receiving device 300, and the two are slidably engaged with the second side. The position of the movable reflector body 240 can be adjusted to change the beam propagation distance, adapting to beam testing of different laser bodies 001 under test. Since the relative positions of the movable reflector body 240 and the beam receiving device 300 remain unchanged, the beam reflected by the movable reflector body 240 can always be received by the beam receiving device 300.

[0056] For example, the movable reflector body 240 and the light spot receiving device 300 can both be mounted on the adjusting plate 250. The adjusting plate 250 is provided with a snap-fit ​​protrusion that can engage with the corresponding snap-fit ​​hole 212 on the second side. By adjusting the position of the adjusting plate 250, the positions of the movable reflector body 240 and the light spot receiving device 300 can be adjusted. Furthermore, the snap-fit ​​hole 212 and the snap-fit ​​protrusion can be designed as a foolproof structure to prevent incorrect assembly of the adjusting plate 250 from causing errors in the beam propagation distance. For example, the snap-fit ​​hole 212 and the snap-fit ​​protrusion can be irregularly shaped, allowing only one type of engagement.

[0057] In other embodiments, the light spot receiving device 300 can be configured to slide in conjunction with the adjusting plate 250, adjusting the relative position of the light spot receiving device 300 and the movable reflector body 240 in the horizontal direction, so that the light beam reflected by the movable reflector body 240 can be better directed towards the light spot receiving device 300. For example, a guide rail 260 can be provided on the adjusting plate 250, the length direction of the guide rail 260 being perpendicular to the direction of the light beam from the movable reflector body 240 towards the light spot receiving device.

[0058] For ease of explanation, in this embodiment, there are three first fixed reflector bodies 222, namely a, b, and c. There are four second fixed transmitting mirror bodies, namely d, e, f, and h. a receives the beam emitted from the laser under test body 001, reflects it, and then directs it to d, then sequentially to e, b, c, f, and h, finally passing through h to the movable reflector body 240, and from the movable reflector body 240 to the light spot receiving device 300.

[0059] Obviously, in other embodiments, the number of first fixed reflector bodies 222 is not limited to three, and similarly, the number of second fixed reflector bodies 232 is not limited to four, etc.

[0060] The laser performance testing system provided in this embodiment can obtain the changes in energy and beam divergence angle of the laser body 001 under different temperature environments by adjusting the working state. Based on the obtained test results, the system can guide the improvement of the laser body, thereby obtaining a laser with stable performance and strong environmental adaptability.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
