Concept of terawatt picosecond CO2 laser for investigation of the laser radiation interaction with a matter

摘要

In the report building and application questions of picosecond terawatt CO_2 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 urn 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 CO_2 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.
