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。
Reported a laser device with an output power of the order of 40 J. The device is separated from the star laser device as a light source, which consists of three parts: an amplifier chain, an energy system and a supporting truss. The simulation results of the whole laser device show that the gain of the device is enough to output 4 0 J, and the B integral satisfies the requirement of ΔB less than 1 .8. A new all-cavity water-cooled amplifier was developed to measure the small signal gain and gain uniformity. The gain coefficient β was 0.344 cm -1 and the gain uniformity was 91.84%. The results show that this amplifier can fully meet the design requirements of this laser device.
