利用CCD增益测试系统对一台闪光灯抽运、通光口径为 2 9cm× 2 9cm的新型高功率固体激光阵列式片状放大器的增益分布进行了实验测试 ,在充电电压为 2 3kV、抽运能密度为 11J/cm3 的条件下 ,新型 4× 2× 3阵列式片状放大器全口径范围内的小信号增益系数的峰值与平均值之比为 1.10∶1。
The gain distribution of a novel high power solid state laser array chip amplifier with a flashlight pump and a light-emitting aperture of 29 cm × 29 cm was experimentally tested with a CCD gain test system. At a charging voltage of 23 kV, the pumping power At a density of 11 J / cm3, the ratio of the peak to average values of the small signal gain coefficients over the full aperture of the new 4 × 2 × 3 array chip amplifier is 1.10: 1.
