摘要

Active mode-locking itself provides pulses not shorter than picoseconds, Nevertheless, this regime is useful for many laser systems including powerful ones where strict synchronization with external periodic signal is needed, Another growing field where active mode-locking is widely used is fiber laser systems. 30 years passed since D.Kuizenga and A.Siegman (K-S) developed their (presently well-known) theoretical model for active mode-locking, Hence many other models have been published, all of them (including K-S) are not completely adequate for the real laser systems. That conclusion was pointed out by one of the authors for the gas, dye and solid-state lasers and presented in many publications and conference papers. In this paper we present results of successful numerical modelling for the mode-locked Ar-ion laser, which are in qualitative agreement with the experiment. Disagreement of the known models (or not revealed stuff from them) with the experiment can be formulated in such common items: a) an optimum pulse position inside the temporal mode-locker window: de- pendence on the gain, mode-locker parameters; b) phase characteristics (pulse position inside the mode-locker window); c) pulse amplitude and duration versus the mode-locker parameters.
