We manufactured and investigated distributed Bragg reflector ridge-waveguide diode lasers having sixth-order surface gratings and an emission wavelength around 974 nm. The single-mode output power of the lasers with a total length of 4 mm exceeded 1 W. A very small spectral linewidth of 1.4 MHz (3 dB) consisting of a Lorentzian part of 146 kHz and a Gaussian part of 1308 MHz was measured using a self-delayed heterodyne measurement technique.
我们制造并研究了具有六阶表面光栅和发射波长约 974nm 的分布式布拉格反射器脊波导二极管激光器。总长度为 4mm 的激光器的单模输出功率超过 1W。使用自延迟外差测量技术测量了由 146kHz 的洛伦兹部分和 1308MHz 的高斯部分组成的非常小的光谱线宽 1.4MHz（3dB）。
