Passively mode-locked Nd:LuVO 4 laser with a GaAs wafer

We report on the passive mode locking of a diode-pumped Nd:LuVO4 laser with a GaAs wafer as output coupler. Using the interference modulation effect of the GaAs wafer, high-power continuous-wave mode locking with a pulse width of about 7.1 ps and an average output power of 3.11 W was achieved. Our result shows that Nd:LuVO4 could be an excellent gain medium for diode-pumped high-power mode-locked lasers.
