Embodiment 1

[0022] The structure of the solid-state laser source is as figure 1 As shown, it includes a housing 1 , a pump source module 2 , a cylindrical laser gain medium 3 , a full mirror 4 , a half mirror 5 , a pump source module storage bin 6 , a displacement mechanism 7 and a heat dissipation structure 8 .

[0023] The laser gain medium 3 is arranged in the housing 1, and the two end faces of the laser gain medium are respectively covered by a total reflection mirror 4 and a half reflection mirror 5, and two or more pump source modules 2 surround the side of the laser gain medium to form a pump structure, several pumping source modules are stored in the casing, and a displacement mechanism 7 is set in the casing, and after a pump is completed, the pumping source modules surrounding the side of the laser gain medium are automatically replaced by the displacement mechanism.

[0024] The shape of the laser gain medium is optional. When the laser gain medium is installed in place, it is...

Embodiment 2

[0034] The high-energy solid-state laser source of this embodiment has the same basic structure as that of Embodiment 1, but it also has the following differences:

[0035] The laser gain medium is a rectangular columnar structure (slab), such as image 3 As shown, the shell of the pump source module matching the laser gain medium is a cylinder with a rectangular cross section, and the pump source module only surrounds the left and right sides of the laser gain medium to form a pump structure; the upper and lower sides of the laser gain medium The two sides are provided with a heat sink heat dissipation structure for cooling the laser gain medium.

[0036] The transparent casing 9 of the pumping source module 2 is as image 3 As shown in the open quartz glass square tube, the first inner surface 13 of the square tube is provided with a resistive film layer 10 and a chemical flash agent film layer 11 in sequence, and the second inner surface 16 of the square tube is coated wit...

Abstract

The invention discloses a solid-state laser source. A laser gain medium is arranged in a shell. The two end surfaces of the laser gain medium are respectively covered by an all-reflective mirror and a semi-reflective mirror. Two or more pump source modules surround the side surface of the laser gain medium to form a pump structure. A plurality of pump source modules are stored in the shell. A displacement mechanism is arranged in the shell. The displacement mechanism can automatically replace the pump source module surrounding the side surface of the laser gain medium. The pump source module has a transparent shell, and a resistive film layer is arranged on one inner surface of the shell. A chemical flash reagent film layer distributed in a planar shape is arranged on the resistive film layer. Two ends of the shell are closed by an end plug to form a fully closed structure for the pump source module. An electrode is arranged on the end plug. One end of the electrode is connected with the resistive film layer and the other end is connected with an external power source. The solid-state laser source simultaneously solves the problems of chemical flash pump source reagent replacement and combustion residue pollution and achieves high-energy pulse laser output with repetition frequency.

Description

technical field [0001] The invention relates to a solid-state laser source, which can be applied to the field of portable high-energy lasers. Background technique [0002] Portable high-energy lasers with small size and light weight have great application requirements in the field of anti-terrorism security. However, the existing laser technology mainly uses xenon lamp and semiconductor laser as the pumping source. The energy source of the laser is external electric energy. The volume and weight of the power supply system occupy a high proportion in the entire laser system, and it is complex, precise and expensive. Under the conditions of limited load and space on the installation platform, such as a small unmanned aerial vehicle with a load of ten kilograms, it is difficult for the above-mentioned xenon lamp or diode-pumped laser to meet the multiple requirements of high energy, small size, and light weight at the same time. Contents of the invention [0003] The inventi...
