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.
我们报道了一种表征小带宽外腔二极管激光器调谐能力的方法。研究了压电驱动的利特曼 - 梅特卡夫外腔二极管激光器的阶跃响应及其光机电频率响应的补偿。当向压电元件施加一个约50V的补偿高斯脉冲时,观察到失谐为13.6GHz。这种激光器的改进对于多种光谱应用以及作为激光雷达应用的可调谐种子激光器很有用。
