ABSTRACT:
An optical system comprises an optical fiber with gain producing core with an index of refraction n1, surrounded by at least one cladding with an index of refraction n2, said cladding including at least one index reduced area with an index of refraction n2, such that n1>n2>n2, the core propagating a signal at a spatial fundamental mode at a signal wavelength λ1and at a power level sufficient to generate optical power at a wavelength λ2, where λ2>λ1, and the at least one index reduced area in combination with the core provide has at least one cut-off fundamental spatial mode wavelength λC, and λ1<λCand λ2>λC.
