We present data on ridge-waveguide diode lasers having a vertical far-field divergence of only 11.5 degrees (FWHM) owing to an appropriate waveguide design. The lasers emitted an optical power of more than 1 W into the spatial fundamental mode from a ridge width of 5 microm. The emission wavelength was stabilized to a narrow range around 808 nm by placing a volume Bragg grating in front of the outcoupling facet.
我们展示了有关脊形波导二极管激光器的数据，由于采用了合适的波导设计，其垂直远场发散角仅为11.5度（半高宽）。这些激光器从5微米的脊宽向空间基模发射超过1瓦的光功率。通过在输出耦合面之前放置一个体布拉格光栅，发射波长稳定在808纳米左右的窄范围内。
