    • A light source and the method for operating the same are disclosed. The light source includes first and second lasers, and first and second wavelength control assemblies. The lasers emit first and second light beams, respectively, at wavelengths that are determined by first and second wavelength control signals. First and second beam splitters split the first and second light beams, respectively, to create first and second sampling light beams. The first and second wavelength control assemblies receive sampling light beams and generate the first and second wavelength control signals such that the wavelengths of the first and second light beams differ by no more than a predetermined amount. The first and second wavelength control assemblies each include an absorption cell having a gas that has an optical absorption that varies with the wavelength of the first and second sampling light beams at wavelengths around the output wavelength of the light source.
    • 公开了一种光源及其操作方法。 光源包括第一和第二激光器以及第一和第二波长控制组件。 激光器分别以由第一和第二波长控制信号确定的波长发射第一和第二光束。 第一和第二分束器分别分开第一和第二光束以产生第一和第二采样光束。 第一和第二波长控制组件接收采样光束并产生第一和第二波长控制信号,使得第一和第二光束的波长不同于预定量。 第一和第二波长控制组件各自包括具有气体的吸收单元,该气体具有随着在光源的输出波长附近的波长的第一和第二取样光束的波长而变化的光学吸收。
