我们的实验有望为实现光谱光束组合二极管激光棒的超窄线宽提供一种方法。通过光束变换系统，将二极管激光棒的光束组合在一个快速轴上。利用中继光学器件和长焦距1.5 m的变换透镜，可以将光谱组合激光棒的整个波长从10 nm以上缩小到0.48 nm。我们已经实现了56.7 W cw从19元单根杆，M2为1.4（水平方向）×11.6（垂直方向）。这些参数充分证明了来自二极管激光棒的所有光束被组合在一起以增加亮度。
Our experiment is expected to provide an approach for realizing ultranarrow linewidth for a spectral beam combined diode laser bar. The beams of a diode laser bar are combined in a fast axis after a beam transformation system. With the help of relay optics and a transform lens with a long focal length of 1.5 m, the whole wavelength of a spectral combined laser bar can be narrowed down to 0.48 nm from more than 10 nm. We have achieved 56.7 W cw from a 19-element single bar with an M2 of 1.4 (in horizontal direction)×11.6 (in vertical direction). These parameters are good evidence that all the beams from the diode laser bar are combined together to increase the brightness.
