Abstract

The performance of an FOG using a DPB SFS in a laboratory environment is reported, and compared with the one using an SPB SFS. The result shows that the DPB SFS has a larger linewidth and a higher pump efficiency than the SPB one. When measuring the earth rotation rate, the FOG using the DPB SFS has lower random noise and smaller bias drift (0.019 deg/√h and 0.18 deg/h) than that using the SPB SFS (0.023 deg/√h and 0.47 deg/h). If a DPB SFS was applied in the space, its output loss due to radiation damage could be smaller than an SPB one because a DPB SFS used a shorter EDF so that the total radiation induced loss is reduced.
