| 摘 要： | 采用光束整形和空间合束的方法,研制出高功率、高效率多阵列光纤耦合半导体激光模块。将波长为976nm连续工作的5个标准半导体阵列,通过对快轴进行准直和快慢轴光束旋转的方式进行光束整形,准直后进行空间合束,经耦合透镜聚焦,耦合入芯径400μm、数值孔径0.22的光纤。测量结果显示:光纤的出光功率最大可达到327 W,光纤耦合效率大于93.6%。

| Abstract: | The high coupling-efficiency fiber coupled diode laser module is obtained by beam shaping. The wavelength of the CW diode laser bar is 976 nm, and five bars are collimated by a fast axis collimation lens. Then the beams are transformed and collimated by slow axis collimation optics. Then all the beams are combined in space, and focused into a multimode fiber (400 m core diameter, the numerical aperture (NA) is 0.22). Experimental results show that the laser output from fiber could reach 327 W, and the coupling-efficiency is more than 93.6%. Experimental results demonstrate that this module lays a foundation for multi-wavelength, polarization beam combining and the high beam quality, high coupling efficiency diode laser module with CW thousands watts class output power can be developed. |
