Passive Q-switched power laser resonator

摘要

Optical resonator for power lasers, consisting of an active means (3), two totally reflecting cavity mirrors (1,6), a phase shifter (2), a polarizer (4) and a passive Q-switch (5). The passive Q-switch is placed between the polarizer (4) and one of the two cavity mirrors, while the active means (3) and the phase shifter (2) are set between the polarizer (4) and the other cavity mirror. The configuration is meant to reduce the losses introduced by the passive Q-switch, and also to reduce the risk of it being damaged by radiation.
