    Abstract: A mode-monitoring system used in connection with discrete beam frequency tunable laser provides optical feedback that can be used for adjusting the laser or for other processing associated with the use of the laser. For example, the output of a frequency tunable source for a frequency-shifting interferometer can be monitored to support the acquisition or processing of more accurate interference data. A first interferometer for taking desired measurements of optical path length differences traveled by different portions of a measuring beam can be linked to a second interferometer for taking measurements of the measuring beam itself. The additional interference data can be interpreted in accordance with the invention to provide measures of beam frequency and intensity.

    Abstract translation: 与分立光束可调谐激光器相结合使用的模式监测系统提供可用于调整激光器或与使用激光器相关的其他处理的光学反馈。 例如,可以监视用于频移干涉仪的频率可调谐源的输出,以支持获取或处理更准确的干扰数据。 用于取得测量光束的不同部分所行进的光程长差的期望测量的第一干涉仪可以连接到用于测量测量光束本身的第二干涉仪。 可以根据本发明解释附加的干扰数据,以提供射束频率和强度的测量。
