This paper introduces the performances of an ultrastable tunable narrow-band fiber laser and its implementation scheme.Based on the commercially available Er-doped fiber amplifier
fiber Bragg grating and variable optical attenuator
this fiber laser has high output power stability(
<
0.92% within one hour)
narrow linewidth(
<
52pm)
high sidemode suppression ratio(
3
0dB)and large tunable range(over 20nm).The entire system can not only be used as a narrowband fiber laser but also as a wideband amplified spontaneous emission light source and an Er-doped fiber amplifier.Furthermore
this system can be easily realized in an ordinary laboratory.
