摘要： A laser tuning mechanism which embodies “spectrally dependent spatial filtering” (SDSF) and contemplates two key elements of the tuning mechanism. The first element of the SDSF tuning mechanism is a spectrally dependent beam distortion (i.e. alteration of the amplitude and/or phase profile of the beam) provided by an SDSF tuning element in a laser cavity. The second element of the SDSF tuning mechanism is an intracavity spatial filter which makes the round trip cavity loss a sensitive function of both beam distortion and cavity alignment. Such a laser can be aligned so that a specific beam distortion, which is provided by the SDSF tuning element at a tunable wavelength, is required to obtain minimum round trip cavity loss, thereby providing tunable laser emission. A preferred embodiment of the SDSF tuning mechanism is an external cavity semiconductor laser having a zeroth order acousto-optic tuning element.
摘要翻译：激光调谐机制体现了“光谱依赖空间滤波”（SDSF），并考虑了调谐机制的两个关键要素。 SDSF调谐机构的第一要素是由激光腔中的SDSF调谐元件提供的频谱依赖的光束失真（即光束的振幅和/或相位分布的改变）。 SDSF调谐机构的第二个元素是腔内空间滤波器，其使得往返腔体损耗具有波束失真和腔体对准的敏感功能。这样的激光器可以对齐，使得由SDSF调谐元件提供的可调谐波长的特定光束失真是需要的，以获得最小的往返腔损耗，从而提供可调谐的激光发射。 SDSF调谐机构的优选实施例是具有零级声光调谐元件的外腔半导体激光器。

摘要： Stable single mode operation of an external cavity semiconductor laser is obtained by a laser control method that monitors at least one optical beam which is generated by reflection from a wavelength selective element within the laser cavity. The method of the present invention provides stable single mode operation and significantly decreases the mode hop rate, because the signal obtained by reflection from a wavelength selective element within the laser cavity provides a clear indication of an impending mode hop.
