ISKRA Lasers - ISKRA-4

ISKRA-4

The ISKRA-4 laser is a spatially filtered (image relayed) 8 beam photolytically pumped iodine gas laser capable of producing laser pulse energies of around 2 kJ (pulsewidth of about 1 ns) at its fundamental emission wavelength of 1.315 micrometers, though it is also capable of operating in a frequency doubled configuration where it emits light at 658 nm with a pulse energy of around 500 J. ISKRA-4 produced its first thermonuclear neutrons from imploding DT fuel capsules in 1981.
