High-power passively Q -switched Nd:GdVO4 laser with a reflective graphene oxide saturable absorber
Abstract
A single output Q -switched Nd:GdVO4 laser with a reflective graphene oxide (GO) saturable absorber was demonstrated. The shortest pulse duration in the Q -switched laser is 115 ns, and the output power ranges from 1.23 W at 1.71 MHz to 2.11 W at 2.50 MHz when the pump power rises from 7.40 to 10.90 W with the utilization of GO Langmuir–Blodgett (LB) films based on the convenient and low-cost LB technique. To the best of our knowledge, it is the highest output power in a Q -switched laser with a GO saturable absorber.
