摘要： A method of manipulating a laser source, includes analyzing an optical signal generated by the laser source, evaluating on the basis of the analysis an actual indicator corresponding with an actual value of a tuning velocity of the laser source, comparing the actual indicator with a desired indicator corresponding with a desired value of the tuning velocity to detect a deviation of the actual value of the tuning velocity from the desired value of the tuning velocity, and compensating the deviation if any by manipulating at least one parameter influencing the signal of the laser source.

摘要： A wavelength tunable laser unit has a laser mode selection, and is adapted to provide a laser signal in accordance with one or more laser control parameters. For operating the laser unit, the laser signal is swept in a wavelength range, a laser operation signal indicative of the laser unit's operation during the sweep is received, and the laser operation signal is analyzed for detecting an indication of a mode hop occurred in the generated laser signals during the sweep. At least one correction value is determined based on the detected mode hop indication, and at least one of the one or more laser control parameters, applicable for a next wavelength sweep, is modified based on the determined at least one correction value.

摘要： The invention relates to a method of tuning a laser, comprising the steps of: providing a laser beam to an external cavity, the laser beam traveling through material along a path between a cavity end element and a tuning element, the path having an optical path length, selecting at least one mode of the laser by introducing a dispersion element in the path of the laser, rotating the tuning element about a pivot axis theoretically defined by the intersection of the surface planes of the cavity end element, the dispersion element and the tuning element to tune the laser, changing the optical path length of the path in order to at least partly compensate a shift between the real position of the pivot axis and the theoretically defined position.
