摘要： A method and apparatus use a photonic-crystal fiber having a very large core while maintaining a single transverse mode. In some fiber lasers and amplifiers having large cores problems exist related to energy being generated at multiple-modes (i.e., polygamy), and of mode hopping (i.e., promiscuity) due to limited control of energy levels and fluctuations. The problems of multiple-modes and mode hopping result from the use of large-diameter waveguides, and are addressed by the invention. This is especially true in lasers using large amounts of energy (i.e., lasers in the one-megawatt or more range). By using multiple small waveguides in parallel, large amounts of energy can be passed through a laser, but with better control such that the aforementioned problems can be reduced. An additional advantage is that the polarization of the light can be maintained better than by using a single fiber core.

摘要： Apparatus and method for spectral-beam combining of light from a plurality of high-power lasers (e.g., fiber MOPA lasers) that, in some embodiments, use substantially identical diffraction gratings in a 1-D non-parallel, mutually compensating configuration to combine non-parallel converging input beams in one plane each having a slightly different successively higher wavelength into a single output beam of high quality. In other embodiments, an output grating and one or more input gratings in a 1-D parallel, mutually compensating configuration combine non-parallel input beams in one plane into a single output beam of high quality. In other embodiments, a 2-D plurality of input gratings in a non-parallel configuration combine a plurality of non-parallel input beams not in one plane each having a slightly different successively higher wavelength into a set of converging beams in one plane directed towards an output grating that compensates for chromatic dispersions introduced by the input gratings.
