The construction of a CO2 laser system generating a train of sub-nanosecond laser pulses with total train energy of up to 5 J is reported. A record level of laser energy was obtained due to utilization of unique 5 × 5cm2 aperture, and 6 atm X-ray preionized CO2 amplifier. The estimations of individual pulse durations in the train are given. The prospect of upgrading the present configuration of laser systems towards shortening laser pulse duration and increasing the pressure of the working gas mixture of the amplifier and its efficiency are discussed.
