Abstract

We propose and analyze a new mechanism for conversion of noise-like pulses into coherent ones with the help of a Raman process. The conditions that ensure conversion efficiency exceeding 45% were identified. Parameter ranges were established, within which the proposed mechanism can be implemented. We also define the condition of generation of stable Raman soliton molecules. The possibility of efficient conversion of noise-like pulses into coherent ones opens up new broad application fields for high-energy double-scale pulses.
