At first, we made a approximate λ/4-shifted DFB Yb-doped fiber laser with double exposure method. The length of Yb-doped fiber is 10cm. Secondly, we treat λ/4-shifted Yb-doped DFB fiber laser with UV trimming. We observed the running characteristic of the laser with scanning F-P interferometer and oscilloscope at the same time. Finally, we obtained SLM Yb-doped λ/4-shifted DFB fiber laser. The laser threshold is 20mW. When pump power is 130mW, we have gained 25mW SLM laser at 1053nm. Finally, we obtained SLM Yb-doped λ/4-shifted DFB fiber laser. The threshold of which is 20mW. When pump power is 130mW, we obtained 25mW SLM laser at 1053nm.
