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 ( 10 ) is disclosed. The method is characterized by the steps of suppressing the relative output power of a potentially most powerful output wavelength ( 98 ) in a first step ( 108 ), adjusting the relative output power of the shortest output wavelength ( 94 ) in a second step ( 110 ), adjusting the relative output power of further output wavelengths ( 96, 100, 102, 104 ) in a third step ( 112 ), and adjusting the relative output power of the potentially most powerful output wavelength ( 98 ) in a fourth step ( 114 ). Further, a device ( 68 ) that performs such a method is disclosed, i.e. a device for adjusting the relative output power of individual output wavelengths ( 94, 96, 98, 100, 102, 104 ) of such a laser ( 10 ).
