Pumping system for laser source, has mirror with reflectivity peaks to lock operation of diode on one peak upon change in temperature of diode such that system emits beam whose wavelength varies in steps corresponding to preset wavelengths

摘要

The system has a pump diode (12) emitting a pump beam (5) whose wave length varies with temperature, and a collimation unit (13) associated with the diode. A selective mirror (14) selects a wavelength of the diode and has a set of reflectivity peaks for locking the operation of the diode on one of the peaks during a change in temperature of the diode such that the system emits the beam, where the wavelength of the beam varies in steps corresponding to a set of preset wavelengths during the change in temperature.
