利用光纤耦合实现了两个半导体激光器同时纵向泵浦ＮｄＹＡＧ激光器。实验研究了激光器的阈值和激光器输出的光强分布与泵浦光场之间的关系。实验发现当两个半导体激光器采取一定顺序启动时，可以降低固体激光器的阈值 Two fiber lasers are used to longitudinally pump NdYAG lasers simultaneously. Experimental study of the laser threshold and laser output light intensity distribution and the relationship between the pump light field. Experiments found that when two semiconductor lasers to take a certain order to start, you can reduce the threshold of solid-state lasers
