摘　　要：采用氙灯泵浦，实现了掺钕氟磷酸锶晶体（ＮｄＳ－ＦＡＰ）以Ｃｒ４＋ＹＡＧ作为被动调Ｑ元件的１．０５９μｍ激光运转，测量了Ｃｒ４＋ＹＡＧ不同小信号透过率及不同泵浦能量下激光单脉冲的输出能量、脉冲宽度、重复率，给出了ＮｄＳ－ＦＡＰ晶体Ｃｒ４＋ＹＡＧ调Ｑ工作原理的方程组，数值求解该方程组所得的理论结果与实验值相符。Using xenon flash lamp as pump source and Cr 4+ ∶YAG as passive Q switch, we have performed the Q switched laser operation at 1.059 μm with a Nd∶Sr 5(PO 4) 3F crystal and measured the single pulse output energy, pulse width and repetition rate under different small signal transmission of Cr 4+ ∶YAG and, different reflectivity of output reflector. Meanwhile, the Cr 4+ ∶YAG Q switched coupling rate equations for Nd∶Sr 5(PO 4) 3F crystal were given. The numerical solutions of the equations were in agreement with the experimental results.
