Diode-End-Pumped, Passively Q-Switched, Dual-Wavelength, Nd:Yag Crystal Laser With Monolayer Graphene As Saturable Absorber Operating At 1319 And 1338 Nm

A diode-end-pumped, passively Q-switched, Nd:YAG laser with a monolayer graphene as saturable absober simultaneously emitting at 1319 and 1338 nm was demonstrated for the first time. The maximum output power, the minimum pulse duration and the highest repetition rate were 586 mW, 317 ns, and 102 kHz, respectively. The corresponding peak power was about 18.1 W.
