An approximative λ/4-shifted DFB Yb-doped fiber laser was made in the length of 10 cm Yb-doped fiber by double exposure method. Then, it was treated with λ/4-shifted Yb-doped DFB fiber laser with UV trimming. The running characteristic of the laser with scanning F-P interferometer and oscilloscope was observed. SLM Yb-doped λ/4-shifted DFB fiber laser was obtained. The threshold is 20 mW. When pump power was 130 mW, 25 mW SLM laser at 1053 nm was got.
