Abstract
An all-fiber 1.48-mu m generator based on a laser-diode-pumped Yb-doped dou ble-clad laser and a cascaded Raman wavelength converter has been developed . Second-order Raman Stokes radiation was generated in a phosphosilicate-fi ber resonator formed by two pails of Bragg gratings. A slope efficiency of the Raman converter of 48% with respect to the power emitted by the double- clad Yb laser has been achieved. We obtained an output power of 1 W at a sl ope efficiency of 34% with respect to the laser-diode array power, with a t otal optical-to-optical efficiency of 23%.
