Two-dimensional nonstationary models of optical pumping 
of a solid-state laser in the presence of a reflector and heating 
of a cylindrical or plane active element with water cooling have been 
described. The results of calculations of the space-time dependence 
of the pumping rate and the temperature in the active element have 
been given for different versions of a neodymium laser with a crystalline 
active medium in laser-diode pumping.
