Paper Abstract

An experimental setup was established by using a high stability, narrow line bandwidth fiber laser with a fiber optic amplifier, polarization maintaining fiber coupler with split ratio of 50:50 and 95:5 respectively, a fiber optic sensing coil with high birefringence large nonlinear polarization maintaining fiber, and uniform fiber Bragg grating that was used at output port for filtering the excess pumping component. Based on this experimental setup, the threshold power of the pumping laser was deduced, and the relationship of the spectra and intensity between pumping laser component and stokes component with frequency downshift was obtained experimentally.
