Аннотация:A model is developed and numerical calculations are performed for the regenerative amplification of seed picosecond 10-mu m radiation pulses in a high-pressure optically pumped CO2 laser. It is established that by varying the cavity parameters, the conditions of efficient regenerative amplication may be optimised for the case of a relatively short-duration (50 ns) solid-state Cr : Er : YSGG laser and 'long-duration' (250 ns) electrodischarge chemical HF laser, used for pumping. It is shown that the schemes of a CO2 amplifier with optical pumping presented allow obtaining the pulses with the duration of 3 ps,output energy of 1-5mJ, and peak power of similar to 1 GW at the pump energy of 150-200 mJ.
