摘要

The multi-channel laser (1) comprises two optical resonator branches (2,3) with high reflecting mirrors (6,7), where the two optical resonator branches are provided with two active mediums (4,5). An electro-optical Q-switch modulator (12) is provided to control p-polarized light of the active medium (4) passes through a polarizer (14) arranged in path of rays of the resonator branches. Another electro-optical Q-switch modulator is provided to convert s-polarized light of another active medium (5) into p-polarized light.
