Abstract

A novel high-power single-frequency narrow linewidth fiber laser with long linear laser cavity is designed and manufactured by using nonlinear two-wave mixing. The distributed gain gratings and refractive index gratings

which are generated by interfering between the feedback injecting light from the part of output light and the lasing light in intra-cavity

are used to select longitudinal modes efficiently and ensure stable single-frequency operation. A segment Er

/Yb

co-doped double cladding fiber is used as gain medium and is pumped by multi-modes laser diodes (LD) with wavelength of 975 nm

and then stable high-power single-frequency laser at 1 550.63 nm is acquired. The fiber laser exhibits a 356 mW threshold and laser output power is 653.7 mW for a pump power of 3.1 W. Optical-optical efficiency is 21.1%

slope efficiency is 24.6% and signal-to-noise ratio (SNR) is large than 50 dB. The 3 dB linewidth of the fiber laser is about 5.0 kHz

which is measured by the delayed self-heterodyne method with 40 km delayed fiber.
