Paper Abstract

We have demonstrated a passively mode-locked fiber laser with a composite cavity structure for repetition rate control. An optical delay line is used to control the length so that the lengths of the main cavity and the sub-ring cavity are accurately co-prime. Using this method we have obtained 46th harmonic pulses with a fundamental repetition of 17.39MHz. The fundamental mode-locking is substantially suppressed. The SNR of rf spectrum is higher than 45 dB. Stable 800MHz repetition rate mode-locked pulses in duration of 14.27 ps are generated. The detuning phenomenon appears when two cavity’s lengths are not matched. A larger pump power is required to maintain the oscillation.
