Abstract

Multi-pass amplifier technology has become the main development direction of high power solid-state laser devices. It is necessary to adjust and maintain the laser optical path，establish a mathematical model and adjustment scheme for optical path collimation，and set up six-pass amplification using matrix optics method. The mathematical model of the automatic collimation system is used to obtain the analytical expressions of the far and near-field laser spot offset and adjustment. The feasibility of the optical path principle and adjustment method of the auto-collimation system is verified.
