摘要：
An efficient narrow-linewidth single-frequency (SF) Yb-doped all-fiber master oscillator power amplifier (MOPA) laser operating at 1064.3nm is demonstrated experimentally. A ring cavity SF fiber laser is used as the seed source for the MOPA system and the Yb-doped fibers are employed as the gain medium or the saturable absorber. The SF operation is observed to be stable without mode hopping. The highest output power of 266 mW is obtained under the 400 mW pump power with the corresponding slope efficiency of 66.2%. The linewidth of the amplified output laser is approximately 1 kHz and its optical signal-to-noise ratio is over 45 dB.
