| 摘 要： | 实验研究了带外腔反馈注入的宽接触条形激光器，并用光线传输矩阵分析了该外腔结构。利用闪耀光栅及耦合输出反射镜对表面未镀增透膜的半导体激光器构成外腔，选择一定模式的激光反馈注入回激光器，从而限制了其他模式在半导体激光器内的振荡，压缩了激光器输出激光的光谱宽度。当激光器驱动电流为2．7倍阈值电流时，获得230mW输出功率，0．6nm谱宽，单瓣近衍射极限的激光输出。用一平面镜代替光栅作为外腔反射镜，获得了320mW输出功率，1．5nm谱宽的单瓣近衍射极限的激光输出。

| Abstract: | A broad area laser diode (BALD) with external cavity feedback is experimentally investigated and analyzed by using ray transfer matrices. In the experiment, a grating or a plane mirror that is placed at the image plane of the output facet of the BALD is used as an external cavity mirror. By tilting the grating or plane mirror, the certain transverse mode is selected and other transverse modes oscillating in the cavity are limited. With this setup, a single-lobed nearly diffraction-limited laser beam with an output power of 230 mW and a spectral line width of 0.6 nm (300 GHz) is obtained with a grating, while a laser beam with an output power of 320 mW and a spectral line width of 1.5 nm is obtained with plane mirror. |
