摘要	An external cavity laser apparatus and method wherein wavelenght or channel selection (66) is carried independently from adjustment of external cavity optical path length. The apparatus comprises a wavelenght or channel selection tuner (66) and an external cavity tuner, wherein the wavelength tuner is uncoupled from the external cavity tuner. The tuning mechanisms for wavelenght selection (70) and cavity optical path length (68) are configured to operate independently or orthogonally with respect to each other. The wavelength tuner may operate according to a first, channel selection signal, while the external cavity tuner operates according to a second, external cavity adjustment signal. The wavelength tuner and external cavity tuner may operate under the control of the same, or of separate controllers. The channel selection signal may be derived from a look-up table of adjustment parameter data accessed by a controller, and the external cavity adjustment signal may be derived from an error signal from a detector configured to measure external cavity loss.
其他摘要	一种外腔激光装置和方法，其中波长或通道选择（66）独立于外腔光路长度的调节而进行。该装置包括波长或通道选择调谐器（66）和外腔调谐器，其中波长调谐器与外腔调谐器分离。用于波长选择（70）和腔光路长度（68）的调谐机构被配置为相对于彼此独立地或正交地操作。波长调谐器可以根据第一通道选择信号操作，而外腔调谐器根据第二外部腔调节信号操作。波长调谐器和外腔调谐器可以在相同或独立控制器的控制下操作。信道选择信号可以从控制器访问的调整参数数据的查找表导出，并且外腔调整信号可以从来自检测器的误差信号导出，该检测器被配置为测量外腔损耗。
