Progress on developing a petawatt laser source in 10mm region is described. Analysis of optical pumping N 2 O containing active media by pulsed multifrequency HF laser has been performed. It is shown that amplification of ultrashort pulses should be carried out in the gain band centered at 930cm -1 . Amplification of seed ultrashort (~1ps) pulses in atmospheric and high pressure N 2 O (up to 5atm) amplifiers pumped by powerful pulsed HF chemical lasers is theoretically studied. It is shown that N 2 O atmospheric pressure amplifiers can be effectively used for production output energy of 1kJ. We discuss a simple add for subpicosecond N 2 O- laser system to generate joule-level 200 fs pulses with high temporal quality and an overall conversion efficiency of 80%. Petawatt class N 2 O laser could be prospective for strong-field physics applications and production of high energy proton beams upon irradiating gas jets. |
