We report on a diode end-pumped passively Q-switched Nd:YAG ceramic laser. By using a Cr
4+:YAG single crystal with an 80% initial transmission as the saturable absorber, stable Q-switched pulses with a 126-μJ pulse
energy, a 12-ns pulse width, and an 8.4-kHz pulse repetition rate have been obtained. The Q-switching performance of the laser
under different saturable absorption strengths and output couplings was experimentally investigated.
PACS numbers 42.55.Xi - 42.55.Rz - 42.60.By - 42.60.Gd
