Abstract

The invention provides a high-energy, high-stability and high-reliability slab laser. The slab laser comprises a Dove prism, a pyramid, a pumping source, a wave plate, an electro-optic Q-switched crystal, a first polarization splitting prism, a second polarization splitting prism, a first optical wedge, a second optical wedge, a first compensation lens, a second compensation lens and a pyramid compensation wave plate. The resonant cavity adopts a high-voltage variable wave plate coupling output mode, the integrated cavity mirror adopts a Dove prism and pyramid prism combined resonant cavity, and a small-angle double-optical-wedge high-precision rotary collimation resonant cavity is adopted in the cavity, so that collimation of oscillation light in resonance can be realized; the whole structure is simple to debug, in the resonant cavity formed by combining the Dove prism and the pyramid prism, devices in the resonant cavity deform and shift in a severe environment, the function of the resonant cavity is not affected, and the resonant cavity has an auto-collimation function, so that excellent mechanical vibration resistance and high-low temperature environment impact resistance are achieved, and the laser can work normally and stably under severe conditions such as large shock waves, vibration and wide-range temperature changes.
