✦ Synopsis

Diode-pumped acoustic-optical (AO) Q-switched, passively Q-switched, and double Q-switched Nd:KGW lasers were realized, respectively. Their pulse characteristics were researched. Experiments prove double Q-switching laser can generate a symmetric and shorter pulse when compared with purely AO and passive Q-switching. The double Q-switched laser pulse width of 37.7 ns has been achieved at the incident pump power of 3 W.

A diode-pumped acively Q-switched Nd:YdVO~4~ green laser with periodically poled KTP (PPKTP) has been realized. The dependences of pulse width, pulse energy and peak power on incident pump power are measured for the generated-green-light pulses. A rate equation model is introduced to theoretically a

We report an electro-optical Q-switch ultraviolet laser at 355 nm with narrow width and low repetition rate generated by pulsed-diode side-pumped Nd:YAG/KTP/LBO. The single-pulse energy is measured to be 18.7 mJ with a pulse-width of 7.32 ns at a repetition rate of 1 Hz and a pump current of 120 A.

We demonstrate a diode-pumped passively Q-switched and mode-locking intracavity frequency-doubled Nd:GdVO~4~/KTP green laser with a Cr^4+^:YAG saturable absorber. Nearly 95% modulation depth for the mode-locked pulses inside the Q-switched envelope has been obtained. The Q-switched envelope pulses w
