我们报告了一种表征小带宽外腔二极管激光器调谐能力的方法。研究了压电驱动Littman-Metcalf外腔二极管激光器的阶跃响应及其光电频率响应补偿。当对压电元件施加约50 v补偿高斯脉冲时，观察到13.6 GHz的失谐。激光的这种修改是有用的几个光谱应用和可调种子激光激光雷达的应用。
We report on a method for characterizing the tuning capabilities of small-bandwidth external-cavity diode lasers. The step response of a piezo-driven Littman-Metcalf external-cavity diode laser and the compensation of its optoelectromechanical frequency response is investigated. When an approximately 50-V compensated Gaussian pulse is applied to the piezo element, a detuning of 13.6 GHz is observed. This modification of the laser is useful for several spectroscopical applications and as a tunable seed laser for lidar applications.
