摘　　要：首次报道了氙灯泵浦的自激活自倍频NYAB复合功能晶体的BDN染料片调Q运转,获得了自倍频绿光单脉冲.测量了不同L和T_o情况下的绿光脉冲的能量、脉宽和峰值功率.文中还从理论上推导了自激活自倍频晶体调Q激光器的方程组.数值求解方程组,所得的理论数据与实验结果很好地相符.最后,讨论了进一步提高绿光脉冲峰值功率的途径.A dye Q-switched laser with nonlinear active multi-functional crystal NYAB is realized by using xenon flash lamp pumping for the first time. A 0.53μm pulse of 3 ns pulse duration and 1.28mJ energy (6MW/cm2 peak power) are obtained when small signal transmission of dye T0=0.3 and laser resonator length L= 10cm. Meanwhile, the relations between energy, pulse duration, and peak power of 0.53μm the laser pulse and L, T0 are measured. Moreover, the equations describing the mechanism of NYAB dye Q-switched laser in the case of L longer than rod length are derived. The theoretical results obtained by solving the equations are in agrresment with experimental results. In addtion, the ways of increasing the peak power of NYAB Q-switched laser are discussed.
