| Abstract: | The frequency doubled output of a single frequency Nd∶YVO 4 laser centered at λ0=532 nm was used as input pump to excite single mode fused silica fibers with length of 250 m and 920 m, respectively. The study on broadband SRS Stokes spectrum within range of visible spectrum in fused silica fibers was made. The first order to the fourth order SRS Stokes spectra were obtained, and frequency shift peak was at 450 cm-1, 1064 cm-1, 1610 cm-1 and 2168 cm-1, respectively. |
