The spatial and temporal beam characteristics of 5 kW power CW pumped CO2 laser with controllable mirror in the cavity have been investigated. The five-pass unstable cavity with M equals 2 magnification was used, where one of the folding mirrors was replaced by a water cooled flexible mirror based on bimorph piezoelement. The pulse-periodical regime of laser generation in broad frequency range of controlling signals with the 100% beam power modulation depth was realized. The maximal pulse power value exceeding three times the average power level was obtained at 3.8 kHz pulse repetition frequency.
