根据计算得到的双波长激光振荡的阈值条件，激光实验中对全反镜镀制1319和1338 nm的全反膜(其反射率大于99．73%，而对1064 nm激光的反射率约为7%)；输出镜采用对1064 nm强谱线95%的高透过率，而对1319和1338 nm谱线的透过率分别为34．7%，32．5%，有效抑制了强线1064 nm振荡，成功实现了1319和1338 nm Nd∶YAG同时双波长激光脉冲输出。当输入能量为125 J时，1319和1338 nm脉冲双波长激光的单脉冲总输出能量为0．89 J，电－光转换效率为0．71%，斜率效率为0．89%。输出的双波长激光的中心波长分别在1318．8和1338．2 nm处，谱线宽度(FWHM)分别为0．35和0．48 nm，强度之比为36∶44。

On the basis of the calculation result of the simultaneous dual wavelength threshold condition,the reflectivities of reflection mirror were more than 99.73% at 1 318.8 nm and 1 338 nm wavelengths,but about 7% at 1 064 nm;the output mirror was coated with the transmissions of 34.7% and 32.5% at 1 319 nm and 1 338 nm,respectively,the transmittance of the output mirror was 95% for 1 064 nm laser in the experiment. The strongest 1 064 nm line was effectively suppressed and a 1 319 nm and 1 338 nm dual wavelength Nd∶YAG pulsed laser was successfully developed. The output energy of 0.89 J was obtained at the pump energy of 125 J with the total efficiency of 0.71 % and the slope efficiency of 0.89%. The central wavelengths of the output laser are 1 318.8 nm and 1 338.2 nm with the FWHM of 0.35 nm and 0.48 nm,respectively. The intensity ratio of 1 319 nm to 1 338 nm wavelengths is 36 ∶44.
