Laser resonator with passive Q-switching through a saturable absorber

摘要

Laser cavity with passive Q-switching by saturable absorber (absorbent) and laser incorporating this cavity. This laser cavity includes a solid active medium (7, 12, 22, 21, 211, 213), a saturable absorber (8, 13, 21, 212), an input mirror (14) and an output mirror (15). The saturable absorbent is a thin layer of saturable absorbent material deposited directly onto the solid active medium. The laser includes such a cavity and means for pumping this cavity. IMAGE
