在这项工作中，我们描述了一个简单的外腔激光二极管配备了一个反馈控制系统，其中一个高分辨率的位置敏感探测器检测腔内光的轻微错位。我们的系统不仅提供了一个稳定的波长，可以在1.87 nm的最大扫描范围内调谐，而且还允许更快的扫描，通过精确控制腔内的反射角度。同时控制外反射镜的旋转角度和注入电流，实现了波长的连续调谐。
In this work we describe a simple external-cavity laser diode equipped with a feedback control system, in which a high-resolution position-sensitive detector detects the slight misalignment of the light within the cavity. Our system not only provides a stable wavelength that can be tuned within a maximum scanning range of 1.87 nm, but also allows for faster scanning, through precise control of the reflection angle within the cavity. The simultaneous controls on the rotation-angle of the external mirror and the injection current enabled us to realize continuous wavelength-tuning.
