Asterix IV laser
From Wikipedia, the free encyclopedia
The Asterix IV laser in Prague (commonly reffered to by the acronym PALS for Prague Asterix Laser System) is a high power photolytically pumped iodine gas laser which is capable of producing ~300 to 500 picosecond long pulses of light at the fundamental line of 1.315 microns 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. PALS is open to both domestic and foreign researchers.
