    摘要： An external cavity diode laser system includes a thin film filter. The output facet of the laser diode is coated with a partial reflection coating and the cavity side facet is coated with an anti-reflection coating. A roof-top prism or corner cube retroreflector serves as the laser cavity end reflector and provides stability of the wavelength of the output over time. The laser cavity lies between the partial reflective coated facet of the laser diode and retroreflector. A collimating lens and a thin film filter are located between the end reflector and the laser diode cavity side facet. The lasing wavelength can be adjusted during either manufacture or operation by tilting the filter. Also included is thermal compensation in the mounting for the retroreflector to compensate for thermal movement of the laser system cavity.

    摘要： A system is provided for producing wavelength tunable laser light and a signal indicative of the wavelength of the produced laser light; a laser cavity includes an optical gain medium and a wavelength selective element disposed in a path of light emitted by the optical gain medium such that changing a position of the element changes a wavelength emitted by the medium; a position sensor that senses position of the element; position signal circuitry that produces a position signal indicative of position of the element sensed by the position sensor; a storage medium storing at least one position signal corresponding to a respective predetermined position of the element; comparison circuitry for comparing the produced position signal with the at least one stored position signal and for producing a comparison result indicative of whether the element has reached to the predetermined position; marker signal circuitry providing an external wavelength marker signal when the comparison result indicates that the element has reached the respective predetermined position.
