A 1123 nm ceramic Nd:YAG laser passively Q-switched by graphene grown on SiC wafer was demonstrated. With a pump power of 8.1 W, an average output power of 332 mW was obtained, corresponding to an optical-to-optical conversion efficiency of 4.1% and a slope efficiency of 7.8%. The pulse width was 875.7 ns with a pulse repetition rate of 46.8 kHz.
