Abstract

A polarization additive pulse mode-locked stretched-pulse erbium-doped fiber ring laser with a regenerative feedback producing near transform-limited femtosecond pulses is reported. The regenerative feedback makes use of an intensity modulator driven at twice the fundamental repetition rate of the passively mode-locked fiber laser. The laser is self-starting for a limited range of pump power. The de-chirped pulses have a duration of 90 fs (FWHM) and a pulse time-bandwidth product of 0.44. The pulse energy amounts to 0.3 nJ. Pulses with nearly twice that energy could be obtained, though without self-starting capability. The laser RF power spectrum measurement yields an amplitude noise as low as 0.15% (rms) and a pulse timing jitter of 150 fs (rms). In addition, RF spectra show no relaxation oscillation in the self-starting regime.
