Abstract

The behavior of a passively mode-locked soliton laser, under different energy states, is studied by using a numerical simulation. The shorter pulse obtainable is determined, pointing out the soliton properties of the output pulses. In the case of harmonic mode-locking, power quantisation related to the number of existing pulses in the cavity, is obtained and repetition rate instability is detected. It is found that by introducing a narrow band optical filter in the cavity and by optimising the filter bandwidth, this instability is substantially reduced.<>
