High repetition rate, low jitter, low intensity noise, fundamentally mode-locked 167 fs soliton Er-fiber laser.

A fundamentally mode-locked soliton Er-fiber laser generating 167 fs pulses at 194 MHz via polarization additive-pulse mode locking is demonstrated. This simple, compact, and high repetition rate source exhibits a low timing jitter of 18 fs [1 kHz, 10 MHz] and the lowest relative intensity noise of less than 0.003% [1 kHz, 10 MHz] observed from an Er-fiber laser.
