| 摘 要： | 对于单模ＧａＡｌＡｓ半导体激光器，使用一种简单的闪耀光栅外部弱反馈构型，迫使其工作在８５２．１１ｎｍ波长处，得到了２．２ＧＨｚ的频率连续调谐范围，获得的输出功率约为半导体激光器自由运转时的９０％以上。

| Abstract: | A new
type weak feedback from a blazing grating in Littrow configuration was usedto force a single mode
GaAlAs semiconductor laser to run at 852.11 nm. The frequency tuning range of 2.2 GHz around
852.11 nm and the output power higher than 90% of total power in the case of free running were
obtained. |

| Keywords: | single mode GaAlAs semiconductor laser blazing grating weak external feedback frequency tuning |
