Abstract :
The amplitude noise characteristics of femtosecond optical pulses generated from a synchronously pumped all-fiber Raman soliton laser with high-Q cavity are investigated under different operation states of the laser. By suppressing the soliton self-frequency shift (SSFS) effect in the high-Q fiber cavity, real femtosecond soliton oscillation can be obtained in the laser. Low-noise 400 fs optical pulses with a white amplitude noise level of -120 dBc/Hz have been generated from the laser operating in such an SSFS-free state.<>
