Analytical Model of CW Pumped Passively Q-switched Laser

Popis výsledku v původním jazyce

An analytical model of a CW pumped passively Q-switched laser in plane wave approximation is presented. The model was based on possibility to express the analytical solution of simplified rate equations with the help of Lambert function. The significantsimplification of saturable absorber dynamics is made and its presence is described only by its initial and saturated transmission. Using this model it is possible to estimate giant pulse parameters, like pulse length and energy density, the pulse repetition rate, and the laser input-output power characteristic. The validity limits of this model were verified using numerical solution of more complicated rate equations model which included nonlinear response of the modulator. The model was compared withexperimental results obtained for passively Q-switched diode pumped Nd:YAG/V:YAG microchip laser.
