Paper Abstract

A fairly complex kinetic model was constructed to describe a free-running regime of iodine photodissociation laser at slow pumping. The slow pumping means that the pumping time is longer than the characteristic time of sound propagation across the cross-section of the laser tube, but the acoustic perturbation does not interfere with the inversion population inducing just the refraction index gradient. In this contribution the time variations of the refraction index are projected in the time dependent internal loss of the resonator, which renders temporal variations of the generated pulse or even a break in the generation. Internal loss modulation is derived from measured temporal development of active medium optical aberrations. The resulting free-generation pulse is compared with the measured one.
