摘　　要：报道了一台输出能量在 4 0 J量级的激光装置。该装置从星光 激光装置分光作为光源 ,由放大器链、能源系统和支撑桁架等三大部分构成。对整个激光装置的模拟计算结果表明 :装置的增益能力足够输出 4 0 J,B积分满足 ΔB小于 1 .8的要求。研制了一种全腔水冷新型放大器 ,对其小信号增益系数和增益均匀性进行了测量 ,实验得出增益系数 β为0 .0 34 cm- 1 ,增益均匀性为 91 .84 %。结果表明这种放大器完全能满足此激光装置的设计要求。A 40J laser system, which is called Beamlet', is built at XingguangⅡl aser facility. The system's source is split from XingguangⅡlaser facility and includes an amplifier chain, an energy supply system and a support shelves. The results of analog calculation for the whole system indicate s that the gain is large enough for the design of 40J and ΔB less than 1.8. A new type of whole cavity water co oling amplifier is applied in this system. The experiments of small signal gain factor and gain homogenization on s uch amplifier show that the gain factor β is 0.034cm 1 and gain homogenization is 91.84%.The result indicates the new type amplifier is fit for the design requirement of the laser system.
