Toward 1-TW train of 10-μm picosecond laser pulses

Abstract

The results of principal upgrade of high-pressure, X-ray preionized TE-CO2 laser towards obtaining 10 atm volume self-sustained discharge in CO2:N2:He mixtures with reasonably high (up to 25%) percentage of molecular gases are reported. The estimated energy of radiation from such a laser is greater than or equal to 15 J. It corresponds to peak power of regeneratively amplified 2 ps 10 micrometer pulse formed in master oscillator of laser system greater than or equal to 1.5 TW.
