Laser amplifier for picosecond CO<sub>2</sub>facilities of terawatt power level

A Cherenkov wake confined by perfectly reflecting transverse walls is amplified if the dielectric medium is active. Because of the multiple-reflections process, the effective gain of the wake is enhanced compared to a ray propagating in a straight line. Higher enhancement occurs when the electron velocity is close to the Cherenkov velocity. This Cherenkov wake can then accelerate a second bunch of electrons trailing the first. Gradients larger than 1 GV/m are predicted before saturation becomes a major impediment.

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.
