The ISKRA-4 and ISKRA-5 lasers are
ISKRA-4
The ISKRA-4 laser is a spatially filtered (image relayed) 8 beam photolytically pumped
ISKRA-5
The ISKRA-5 laser is a spatially filtered (image relayed) 12 beam photolytically pumped iodine gas laser capable of producing laser pulse energies of around 30 kJ and peak pulse powers of around 100 terawatts (pulsewidth about 0.25 ns) at its fundamental emission wavelength of 1.315 micrometers. ISKRA-5, like ISKRA-4, also has the capability for frequency doubling to the second harmonic. Maximum fusion yield on ISKRA-5 is about 1010 to 1011 neutrons per target shot.
ISKRA-6
ISKRA-6 is a laser under investigation for future construction by VNIIEF which would be in the near-NIF and LMJ class of extremely high energy, high power frequency tripled Nd:glass lasers used to access the ignition regime of imploding DT fusion fuel capsules for nuclear weapons research. ISKRA-6 would be a 128 beam laser capable of irradiating targets with ~300 kJ of laser light at the 351 nm third harmonic with pulsewidths of around 1 to 3 ns.
