 Asterix IV laser

The Asterix IV laser in Prague (commonly referred to by the acronym PALS for Prague Asterix Laser System) is a high power photolytically pumped iodine gas laser capable of producing ~300 to 500 picosecond long pulses of light at the fundamental line of 1.315 micrometres wavelength with a total energy of about 1 kilojoule (or tripled to the third harmonic at 438 nanometers with lower pulse energies) and peak powers of around 3 terawatts.There are also two smaller auxiliary beams capable of producing 100 J pulses.
