Competition between Stokes and anti-Stokes waves in Raman Fiber Laser

Tóm tắt

The set of intracavity field equations describing the evolution of intra-cavity pumping, Stokes and anti-Stokes powers of Raman laser is presented. Most attention is given to intra-cavity competition of two Raman waves, which depends on cavity properties, frequency shift and phase mismatch. The calculated results are based on Ge-doped and D2-gas-in glass fiber lasers at CW-regime and pulse-pumped regime.
