ABSTRACT:
A single-mode fiber-coupled multi-wavelength laser, wherein, for suppressing higher order transverse modes of the laser cavity than TEM.sub.oo of at least one laser emission wavelength or for increasing the beam waist diameters of the transverse laser cavity modes or for increasing the signal-to-noise level of the output of the laser at least at one emission wavelength, one or more of the following is selected:
