| Abstract: | The output characteristics of linear cavity Yb-doped double-clad fiber (DCF) laser have been studied theoretically and experimentally, including the effects of fiber length, loss, and reflectivity of fiber Bragg grating (FBG) as the output mirror on laser output power and threshold pump power. The linear cavity is composed of a pair of fiber Bragg gratings. A taper fiber is used to reduce the connection loss between DCF and laser diode. With the all-fiber cavity designing, the threshold power is 300 mW. Under the pumped power of 17 W, the single-mode laser output power at 1 070 nm will reach up to 10.5 W with a slope efficiency of 62%. |
