We report the stabilization of a laser diode by external phase-conjugate feedback from a broad-area laser diode. The linewidth of the stabilized laser diode was reduced from 5 MHz to 25 kHz, approaching the limit set by the fluctuations of the pump beam for the phase conjugator. Clear evidence of phase conjugation was the observation of paired half-axial side modes spaced at frequencies of c/4L with respect to the main mode.
我们报道了通过来自宽面激光二极管的外部相位共轭反馈实现激光二极管的稳定。稳定后的激光二极管线宽从5 MHz降低到25 kHz，接近相位共轭器泵浦光束波动所设定的极限。相位共轭的明确证据是观察到相对于主模在频率为c/4L处间隔的成对半轴边模。
