Using a novel silver nanorods absorber with a localized surface plasmon resonance absorption peak at 1.06 μm,we obtain a diode-pumped passively Q-switched(PQS) Nd,Gd:CaF_2 disordered crystal laser output. Its PQS pulse laser performances are studied comprehensively and systematically in this Letter. The single pulse energy and peak power can be attained to 2.15 μJ and 2.06 W, respectively. 相似文献

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. 相似文献
