摘要
介绍了高功率固体激光驱动器中单通片状放大器 (SSA)的模拟和实验研究结果。对放大器能量传输的各环节进行全系统模拟 ,在能源系统优化的前提下 ,对不同抽运条件和不同抽运腔构型放大器的增益特性进行实验研究 ,2 2kV工作电压下 ,获得了 4 9%cm-1的小信号增益系数和 2 4 3%的储能效率。同时还分析了放大器的抽运热畸变及波前变化 ,实验测量了由抽运引起的腔内洁净度变化情况。
The Simulation and experimental results of single segment amplifier (SSA) used in high power laser system are introduced in this paper. By optimizing the pumping constructs of SSA, about 4.9% cm-1 small signal gain efficiency and 2.4% storage energy efficiency have been obtained when working voltage is about 22 kV. At the same time, the thermal distortion and wavefront changing are investigated, and the changing of cleanliness in pump cavity is measured.
