“…Excess of pump leads to the divergence aggravation. According to the calculations, for the height h2 mm and the same radius of the mirror, the total energy of higher (3,5,7) modes is about 1% of that of the basic mode. The images were taken by the matrix ofphotosensors (SPIRICON production), providing the possibility ofreal-time observation ofradiation power re-distribution from the basic to the nearest third symmetrical waveguide mode.…”

For the various pumping rates and for the various heights of the gap were calculated the average value of the small-signal gain and its profile across the gap. For the high power slab C02-lasers, RF-excited at 40.68 MHz, were analyzed the ranges of their geometry parameters variation, providing for the possibility of diffraction limited performance. In theory and in experiment was shown the possibility to select the basic waveguide mode of radiation.
