Abstract
The invention relates to the field of laser engineering and fiber optics and is industrially used to pump optical amplifiers used in wide band fiber-optical communication systems. The subject matter of the invention is a Raman fiber laser based on a phosphosilicate fiber, comprising a pumping radiation source 1, a length 2 of a phosphosilicate fiber, at least two pairs of Bragg gratings as reflectors 3 and 4, wherein each pair of Bragg gratings forms an optical resonator, wherein the transmission of energy between the resonators is effected due to stimulated Raman scattering, both at relatively high frequency intramolecular oscillations, related to the presence of phosphorus oxide in the fiber (the frequency difference of such resonators being selected from the range of 1305-1355 cm.sup.-1), and at relatively low frequency oscillations related to a silicate matrix of the fiber, the shift of frequencies between such resonators being selected from the range of 50-560 cm.sup.-1.
