Abstract

The invention provides a fixing assembly of a pumping module and a laser. The fixing assembly comprises a shell, a radiator, a refrigerator and a fan assembly. A resonant cavity and a mounting cavityare defined by the shell, and a flange for separating the resonant cavity from the mounting cavity is arranged on the inner wall of the shell. The radiator is located in the mounting cavity. Part of the radiator abuts against the flange, and the end, facing the resonant cavity, of the radiator is connected with the pumping module. The refrigerator is located between the radiator and the pumping module. The fan assembly is connected with the shell, and the end, facing the resonant cavity, of the fan assembly abuts against the end, away from the resonant cavity, of the radiator. According to thefixing assembly of the pumping module, the radiator is fixed and limited through the fan assembly and the flange of the shell; the problems that due to the fact that the radiator is fixed to the shell through screws, mechanical deformation happens to the shell, a resonant cavity is detuned, and laser output energy is reduced can be avoided; and moreover, the fixing assembly is simple in structureand convenient to assemble.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a fixing component of a pump module and a laser. Background technique [0002] Laser diode (LD)-pumped all-solid-state laser (DPSSL) has become the mainstream direction of solid-state laser development because of its advantages of high efficiency, long life and compact structure, and has been used in laser processing, laser ranging, target indication, laser Widely used in radar and other fields. [0003] For most types of airborne, vehicle-mounted or handheld high-peak-power pulsed lasers, the miniaturization and light weight of the laser are required. The laser is composed of a laser resonator, a laser diode pump source, a Q-switching component, a power supply system, a temperature control system, and a beam expander system. Usually, the laser uses a metal casing as the supporting structure of the laser resonator, and the optical components are fixed to the metal casing through...
