Реферат:	eng: Second harmonic generation (SHG) of a random laser operating at 1308 nm via Rayleigh backscattering in a phosphosilicate fiber with Raman gain has been studied. SHG power of > 100 mW at 654 nm has been obtained in PPLN pumped by similar to 7 W laser power. The SHG beam is stable, herewith its spectrum has no mode structure within similar to 0.5 nm bandwidth that is different from conventional Raman fiber laser with linear cavity. Direct comparison of SHG in two laser configurations demonstrates better parameters of the random laser having great potential for imaging and other applications requiring low-coherent visible light.
