Passive Q-switching performance with Co:LMA crystal in a diode-pumped Nd:LuVO 4 laser

A diode-pumped passively Q-switched Nd:LuVO 4 1.34 μm laser using Co:LMA saturable absorber was successfully demonstrated. The average output power, pulse width, repetition rate of a-cut and c-cut Nd:LuVO 4 lasers were studied with different output couplers. The maximum average output power of 164 mW was obtained at the pump power of 10.3 W and the narrowest pulse width of 168 ns was achieved at repetition rate of 457 kHz under pump power of 8.59 W in a-cut Nd:LuVO 4 laser with T = 8%.
