摘要

我们报告了一种锁定输出波长并减少二极管激光器谱线宽度的方法，该方法通过从波长选择的外部光学腔向发射器反馈光。十年前，我们的团队开发了一种阶梯式反射镜，通过平衡每个发射器和光栅之间的路径长度，使单个外部腔能够锁定一堆二极管阵列棒的波长。在这里，我们报告将一个这样的步进镜外腔与功率分压器阵列相结合，每个分压器将该反馈功率的一部分发送到单独的二极管阵列棒堆栈。

Power scaling of a wavelength-narrowed diode laser system for pumping alkali vapors

We report a method for locking the output wavelength and reducing the spectral linewidth of diode lasers by feeding back light to the emitters from a wavelength selective external optical cavity. Ten years ago our team developed a stepped-mirror that allowed a single external cavity to lock the wavelength of a stack of diode array bars by equalizing path lengths between each emitter and the grating. Here we report combining one such step-mirror external cavity with an array of power dividers, each sending a portion of this feedback power to a separate diode array bar stack.
