摘　　要：在普通被动调Q激光器中引入抗共振环(ARR)结构。以Cr4+:YAG晶体、BDN染料片和LiF:F-2色心晶体作为可饱和吸收体,采用平面-ARR介稳腔和凸-ARR非稳腔,得到了输出能量大于80mJ、起伏小于1.5%的高稳定大能量调Q单脉冲输出。利用ARR的光栅效应和饱和吸收的机理很好地解释了实验结果。A anti-resonant ring(ARR) was introduced to a conventional passively Q-switched laser. Cr4+:YAG crystal, BDN dye film and LiF:F2- color center crystal were selected as saturable absorbers. Plane-ARR critical resonator and convex-ARR unstable resonator were adopted in our experiments. High stability and large energy single Q-switched pulses with energy greater than 80 mJ and fluctuation less than 1.5% were obtained, respectively. The results were explained well by the grating effect of ARR and the excited state absorption of saturable absorber.
