Paper Abstract

A graphene passively Q-switched single frequency Ho:YAG laser was demonstrated. Ho:YAG crystal was resonantly pumped by a 1908 nm diode laser. Twisted-mode single frequency technique was applied to realize single frequency oscillation. The maximum single frequency laser output was 358 mW. Single frequency pulse laser output was achieved by inserting a graphene into the single frequency Ho:YAG laser. The maximum average power of 149 mW was obtained with the pulse repetition rate of 40.45 kHz under 8.32 W of incident pump power.
