Paper Abstract

Modeling of self-diffraction pattern formation from the induced diaphragm, arising in the case of the transparency channel saturation by one-photon resonant non-stationary excitation of the basic exciton transition in colloidal quantum dots (QDs) is realized. The simulation results allow us to obtain the reference image of self-diffraction pattern and dependence of the intensity transverse distribution of the output beam from the intensity of the excitation beam, forming a transparency channel. A powerful laser pulse creates a transparency channel, so that it self-diffracts on the induced diaphragm. The possibility to apply the obtained simulation results for intensity estimation of the laser radiation and for the possible application in the technique (nonlinear-optical limiters of intense laser radiation in the visible and nearinfrared region, optical switches) are discussed.
