SYNCHRONOUS-PUMPED RAMAN ALL-FIBRE PULSED LASER BASED ON QUARTZ OPTICAL FIBRE DOPED WITH PHOSPHORUS OXIDE

摘要

FIELD: laser engineering.SUBSTANCE: invention relates to laser equipment. Synchronous-pumped Raman all-fibre pulsed laser based on quartz optical fibre doped with phosphorus oxide, comprises a linear resonator formed by two Bragg gratings, one Bragg grating of resonator completely reflects radiation of a first Stokes component of Raman scattering of phosphorus oxide, and other grating reflects it partially to output radiation from resonator. Active medium used is a piece of quartz optical fibre, doped with phosphorus oxide. Pumping radiation source is a pulse source with radiation pulse duration from 100 to 240 picoseconds, wherein length of optical fibre is in range of 1-100 m.EFFECT: technical result consists in production of laser radiation pulses at a first Stokes component of phosphorus oxide with duration shorter than 300 picoseconds.6 cl, 2 dwg
