摘要：

A novel Nd, La:SrF2disordered crystal is prepared, and its continuous-wave wavelength tuning operation is performed for the first time. Employing a surface plasmon resonance(SPR) based gold nanobipyramids(G-NBPs) saturable absorber,we obtain a compact diode-pumped passively Q-switched Nd, La:SrF2laser. The stable Q-switched pulse operates with the shortest pulse duration of 1.15 μs and the maximum repetition rate of 41 k Hz. The corresponding single pulse energy is 2.24 μJ. The results indicate that G-NBPs could be a promising saturable absorber applied to the diode-pumped solid state lasers(DPSSLs).
