Intracavity frequency-doubled passively mode-locked Nd: LuVO 4 green laser

We demonstrated an intracavity frequency-doubled passively mode-locked Nd:LuVO 4 -LBO green laser with SESAM as the saturable absorber. The maximum average output power was 385 mW when the pump power was 9.3 W. The pulse width was 17.6 ps and the repetition rate was 76 MHz. The optical conversion efficiency from the pumping diode laser to the green laser was 4.1%. We observed the interference of the frequency-doubled green light with the normal operation of SESAM, analyzed the reason, and eventually resolved the problem.
