测量了新型晶体ＮｄＳ－ＦＡＰ，［ＮｄＳｒ５（ＰＯ４）３Ｆ］的非偏振光吸收光谱。它具有宽的有效吸收带，在５７５ｎｍ和８０４．５ｎｍ处有二个强的吸收峰。采用微型氙灯泵浦实现了自由运转和染料片调Ｑ运转。激光输出波长为１．０５９μｍ。自由运转的阈值能量仅为１５０ｍＪ，斜效率为１．２５％；调Ｑ输出的峰值功率密度为１０ＭＷ／ｃｍ２。测量了发射光谱及不同腔长、不同染料片小信号透射率情况下的输出能量、脉冲宽度等。 The non-polarized light absorption spectra of [NdSr5 (PO4) 3F] of the novel crystal NdS-FAP were measured. It has a broad effective absorption band with two strong absorption peaks at 575 nm and 804.5 nm. Miniature xenon lamp pump to achieve free operation and dye film Q operation. Laser output wavelength of 1.059μm. The free-running threshold energy is only 150 mJ and the ramp efficiency is 1.25%. The peak power density of the Q-switched output is 10 MW / cm 2. The emission energy, pulse width, etc. were measured for different emission spectra and different cavity lengths and different small dye transmittance.
