| Abstract: | A new connecting way was done in Yb 3+ doped fiber laser, in which a Yb 3+ doped fiber was located at an unpumped place. Narrow linewidth lasing was obtained by using of a bandpass filter and the unpumped Yb 3+ doped fiber acted as saturable absorber. The linewidth of output laser was less than 0.07 nm. The effect of unpumped dopant fiber saturable absorber in Yb 3+ doped narrow linewidth fiber laser was researched in detail. |
