In the report building and application questions of picosecond terawatt CO2 laser installations are presented. The
design and the description of the basic components of middle-infrared picosecond laser facility (MIRPLF) with terawatt
power of 10 &mgr;m laser radiation manufacturing by efforts of institutes NIIKIOEP and NIIEFA are presented. The main
attention is paid to questions of design of the master oscillator with pulse with 10÷100 ps and the final laser CO2 high
pressure amplifier (HPA) with the intermediate water capacitor integrated in to the gas-discharge chamber. The main
results of experimental investigations of characteristics of MIRPLF components are presented and prospects of MIRPLF
projected peak power increasing are analyzed.
The terawatt picosecond CO2-laser design is considered in the paper. The CO2-laser system includes itself the
following units: a) master oscillator with variable pulse width of 100 ps, and b) laser pre-amplifier being developed on a
basis of a ring optical scheme and operating under the gas pressure of 3 atm. Both experimental and theoretical analysis
of the CO2-laser system is carried out.
