测量了 Nd:S-VAP[Nd:Sr_5(VO_4)_3F]晶体的吸收光谱特性,在583.0nm 和809.0nm处有强烈的吸收峰.用可调谐染料激光泵浦实现了低阈值、高效率的激光运转.在透射率15%的平-平腔情况下,斜率效率为50%,阈值2mJ,倍频绿光的中心波长为536.0nm,线宽为1.4nm.采用φ4mm×30mm 的氙灯泵浦,实现了自由运转和染料片调 Q 运转.阈值为130mJ,斜效率为1.3%.测量了不同腔长、不同染料片小信号透射率情况下的输出能量、脉冲宽度以及光束发散角和偏振特性等.
The absorption spectra of Nd: S-VAP [Nd: Sr_5 (VO_4) _3F] crystals were measured and their absorption peaks at 583.0nm and 809.0nm were measured. By using tunable dye laser pumping, the low threshold and high efficiency Laser operation The slope efficiency is 50%, the threshold is 2mJ, the center wavelength of the octave green light is 536.0nm, and the line width is 1.4nm in the case of a flat-flat cavity with a transmittance of 15%. Using a x4mm x 30mm xenon lamp To achieve the free-run and dye Q-switching operation with a threshold of 130mJ and an oblique efficiency of 1.3% .The output energy, pulse width, and beam divergence and polarization characteristics with different cavity lengths and different small signal transmittance were measured Wait.
