摘要： Provided is a laser unit (120) tunable in wavelength, having a laser mode selection, and being adapted to provide a laser signal (110) in accordance with one or more laser control parameters. For operating the laser unit, the laser signal (110) is swept in a wavelength range, a laser operation signal indicative of the laser unit's (120) operation during the sweep is received, and the laser operation signal is analyzed for detecting an indication of a mode hop occured 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.
