At first, Raman wave growth and laser wave depletion are investigated. After that, SRS power thresholds for forward and backward pumpings are determined. Also, we have presented a diagram that we can find threshold power for two-end pumpings. As far as we know, this diagram is represented for the first time M3 ER -
