Abstract

Dynamics of the Q-switched microchip lasers pulse was investigated in experiment with high space and time resolution. It was found that spatial dynamics of the YAG:Nd³⁺/YAG:Cr⁴⁺ microchip laser emission could not be described by traditional formalism of transverse cavity modes. An alternative theoretical approach based on solution of the Maxwell scalar wave equation is presented. In our model we take into account the D_2d local symmetry of the Cr⁴⁺ ions and the corresponding two types of saturable transitions.
