Numerical model for investigation of dynamics of short-cavity short-pulse standing-wave lasers

摘要

Numerical model for calculations of spatio-temporal variations of amplitudes of counter-propagating pulses in a standing-wave laser cavity with gain/absorbing layers with reflecting boundaries is proposed. Proposed model is based on the transport-type equations for the envelopes of oppositely running pulses, spatial discretization along the cavity axis, and calculation of temporal variations both electric field amplitude and active media polarization/inversion at these points. Examples of stationary states and mode-locking regimes are presented.
