Graphene oxide for diode-pumped Tm:YLF passively Q -switched laser at 2 μm
Abstract
A diode-pumped Tm:YLF passively Q -switched laser at 2 μm was first demonstrated by using graphene oxide (GO) as a saturable absorber (SA). In this letter, continuous-wave (CW) laser and pulse laser performances were studied meticulously and systematically. It reasonably showed the dependence of the pulse duration, pulse energy, and pulse repetition rate on the absorbed power. A maximum repetition rate of 38.33 kHz and a single pulse energy of 9.89 μJ were obtained.
