During recent years pulsed CO2 lasers for fusion research have been under construction in the I. V. Kurchatov Institute of Atomic Energy and the D. V. Efremov Electro-Physical Apparatus Institute. Efforts are being concentrated at present on two approaches: (1) microsecond laser pulse plasma heating in solenoids and θ pinches (UTRO system) and (2) nanosecond CO2 laser utilization for inertial confinement fusion. The TIR-1 system was created to develop nanosecond CO2 laser technology and to study laser–target interaction at 10 μm. This system is designed to deliver ~1-kJ energy in one beam of ~1-nsec duration. The TIR-1 system consists of an oscillator–preamplifier system that produces an ~1-nsec laser pulse with an energy contrast ratio of ~106, a large-aperture (30 × 30-cm2) triple-pass amplifier capable of providing ≈1 kJ in a 1-nsec pulse, a target chamber with diagnostic equipment, and associated engineering systems.
