Abstract

The invention discloses an anti-misalignment multiple folded resonant cavity laser, which comprises a total reflection mirror, a corner pyramid turning prism three, a corner pyramid turning prism two, a corner pyramid turning prism one, an output mirror, and a corner pyramid turning prism One and the light-transmitting surfaces of the corner pyramid deflection prism two are arranged oppositely and are perpendicular to each other, the output mirror is parallel to the total reflection mirror, and the λ / 4 wave plate one in the front of the total reflection mirror and the corner pyramid deflection prism three is provided with a λ / 4 wave plate 2, a step-up Q-switching module composed of a Pockel box and a polarizer; the present invention adopts a multiple folded resonant cavity with three pyramid deflection prism reflection structures, which can expand the length of the resonant cavity by more than 4 times, greatly Reduce the volume of the long-cavity long laser, and use the original angle reflection characteristics of the corner-refractive prism to make the laser have excellent anti-misalignment characteristics.

Description

technical field [0001] The invention belongs to the technical field of lasers, and in particular relates to an anti-offset multiple folded resonant cavity laser. Background technique [0002] The cavity length of the laser resonator is an important factor affecting the performance of the solid-state laser. The laser beam quality, divergence angle, Q-switched pulse width, reliability, energy and other parameters are closely related to the resonator length. In general, the longer the resonant cavity, the better the beam quality of the laser, the smaller the divergence angle, and the longer the Q-switched pulse width; but the larger the volume of the laser, the lower its reliability. [0003] In some military laser application fields, such as laser ranging, laser target indication, etc., the Q-switching pulse width of the laser is required to be wide, and at the same time, there are high requirements for the divergence angle, volume, and reliability of the laser. [0004] In s...
