Method for adjusting the output spectrum of a multi-output-wavelength Raman laser

A method for adjusting the relative output power of individual output wavelengths of a multi-output-wavelength Raman laser is disclosed. The method is characterized by the steps of suppressing the relative output power of a potentially most powerful output wavelength in a first step, adjusting the relative output power of the shortest output wavelength in a second step, adjusting the relative output power of further output wavelengths in a third step, and adjusting the relative output power of the potentially most powerful output wavelength in a fourth step. Further, a device that performs such a method is disclosed, i.e. a device for adjusting the relative output power of individual output wavelengths of such a laser.
