Abstract

The possibility of the Raman self-frequency shift [1-3] suppression is of great interest for both the high bit rate communication lines and the lasers with fiber cavities [4]. In the communication lines for picosecond pulses the frequency shifts are small. Frequency drift toward a maximum of the gain profile in an active fibers can compensate to some extent the effect of self-frequency shift. The possibility of frequency stabilization by the effect of frequency pulling under the gain profile was investigated by Blow et al [5]. The frequency pulling to some fixed frequency was predicted instead of the growing with the fiber length soliton frequency shift. The suppression of self-frequency shift due to Raman amplification in the field of external pump wave was experimentally investigated by Gouveia-Neto et al [6].
