High Power Multi-Wavelength Raman Fiber Lasers Using Phosphosilicate Fibers

摘要

We report on the simultaneous Raman lasing of three wavelengths at 1428/1454/1495 nm in a single P-doped optical fibre, by use of the stimulated Raman scattering of both P_2O_2 and SiO_2/GeO_2. Thermally controllable power ratios between the wavelengths have been realized and the maximum total power achieved is 2.87W in a fiber of 700m pumped with an Yb fiber laser of 18W at 10771nm.
