| 摘 要： | 报导了一种使用ｌｉｔｔｒｏｗ配置方法的外腔式半导体激器的调谐方法，通过定义及计算光栅中心波长与外腔模式的误差函数，给出了外腔装配的优化设计。用此方法，实现了光栅外腔式半导体激光２０ｎｍ波长范围的连续调谐。调谐过程中无跳模现象，且也始终保持为单模。

| Abstract: | The method for continuous tuning of diode laser with a grating external cavity called Littrow configuration is analyzed.A optimal design for the alignment of the external cavity is suggested by defining and calculating an error function between the grating pass-band center wavelength and the grating cavity mode.A tuning range of 20nm is achieved without mode hopping,and single transverse mode is always kept during tuning. |

| Keywords: | wavelength tuning diode laser external cavity |
