A passively Q-switched Ho:YVO4 Laser at 2.05 μm with Graphene Saturable Absorber

A passively Q-switched Ho:YVO4 Laser at 2.05 μm with Graphene Saturable Absorber

We report a passively Q-switched Ho:YVO4 laser pumped at 1.94 µm with multilayer graphene as a saturable absorber. At the absorbed pump power of 9.3 W, the maximum average output power of 2.2 W was obtained in Ho:YVO4 laser with minimum pulse width of 265.2 ns and pulse repetition rate of 131.6 kHz...
