Abstract
A laser with an unstable resonator configuration is described with a second, lower power auxiliary laser to provide a feedback beam to pulse high power CW lasers without exceeding the power handling capability limitation of currently available modulators. The present laser relies on adjoint mode feedback provided by the auxiliary laser to accomplish pulsed operation with a modulator in the low power feedback beam path. Higher power output beams can be generated with multiple stages of auxiliary laser providing adjoint mode feedback, thereby reducing incident power on modulation devices while providing adequate adjoint beam power to effectively pulse the high power laser. In certain embodiments a single gain generator is used to drive the main and auxiliary lasers.
