Abstract
A passively Q-switched laser comprises a pump laser diode, a micro laser resonant cavity including a lasing medium and a saturable absorber, a filter and a photodiode. The lasing medium and saturable absorber are bonded together, and dielectric film is coated on the surfaces of the bonded body to form the laser resonant cavity. The filter reflects a portion of the Q-switched laser pulse beam. The photodiode can detect and convert the laser pulse to electric signal for triggering purpose.
