The basic principles for design of an advanced multi-terawatt СО(2) laser system are considered. The key amplifiers' parameters were evaluated by numerical modeling. The potential advantage of using pulsed chemical DF-СО(2) laser as a final amplifier over an electro-ionization TE-СО(2) laser is outlined. The dynamics of noise development along the chain of amplifiers and a resultant contrast ratio are analyzed. The evaluated parameters allowed to suggest a system with a mid-pressure final DF-СО(2) laser which can generate a single 15-TW 2.5-ps pulse.
