532-nm picosecond pulse generated in a passively mode-locked Nd...

A diode-pumped continuous-wave (CW) mode-locked Nd:YVO4/KTP green laser with semiconductor saturable absorber mirror (SESAM) is demonstrated. The maximum output power of CW mode-locked green laser is obtained to be 552 mW at the incident pump power of 7.25 W, corresponding to an optical-optical conversion efficiency of about 7.6%. The 532-nm CW mode-locked pulse duration is estimated to be about 8.4 ps with the repetition rate of 87 MHz.
