Introcavity Dispersion Effect On The Properties Of The Detuned Actively AM Mode Locked Fiber Laser

摘要

The master equation of the actively mode-locked fiber laser is theoretically derived from the time domain for both of the harmonic and rational harmonic AM mode-locked cases when the RF modulating signal is not exactly tuned to the cavity length. It is shown that the existence of the introcavity dispersion will affect the pulse train properties as a function of the normalized detuning. The properties of the pulse train that depend on detuning are the carrier wavelength, the pulse width, the relative phase lag and the frequency chirp.
