| Abstract: | A Er:Yb co-doped silica fiber laser source operating at 1 569.4 nm is reported,with a very narrow 36 pm linewidth laser output.Up to 6 W CW laser power is obtained from an 3.8 m-long Er:Yb co-doped silica fiber,which is cladding-pumped by a 975 nm diode laser.The fiber laser cavity included a high reflective fiber Bragg grating and the other fiber end Fresnel 4% reflection.The slope efficiency is 23.5%,and there is obvious power saturation under high power pumping. |
