介绍了一种基于-1透射式光栅的外腔结构，用于合成970 nm半导体激光棒的光谱光束。获得了50.8W的连续输出功率、45%的电光转换效率、90.2%的光谱合成效率和10.9的整体M(2)值。这为同时具有几个千瓦功率和衍射限制光束质量的半导体激光光源提供了一种方法。
An external cavity structure based on the -1st transmission grating is introduced to spectral beam combining a 970 nm diode laser bar. A CW output power of 50.8 W, an electro-optical conversion efficiency of 45%, a spectral beam combining efficiency of 90.2% and a holistic M(2) value of 10.9 are achieved. This shows a way for a diode laser source with several KW power and diffraction-limited beam quality at the same time.
