本文报道了一台角光栅分布反馈Ⅱ型W激光器在3.4 μm附近获得的近衍射极限输出。在78 K下，50 μ m宽的脉冲光抽运光条的远场光束发散角仅为1.4°。斜效率为64%的传统的法布里-珀罗激光器在同一条。然而，谱线宽度仅减少了2倍。光束质量明显好于法布里-珀罗激光器，条纹宽度至少为800 μm。
We report near-diffraction-limited output from an angled-grating distributed feedback type-II W laser emitting near 3.4 μm. For pulsed optical pumping of a 50-μm-wide stripe at 78 K, the far-field beam divergence angle was only 1.4°. The slope efficiency was 64% of that for a conventional Fabry–Perot laser on the same bar. However, the spectral linewidth decreased by only a factor of 2. The beam quality was substantially better than that for the Fabry–Perot laser out to stripe widths of at least 800 μm.
