In this paper, we report on a new laser facility
called PALS (Prague Asterix Laser System), which is currently
under construction, and which will house the high-power
iodine laser Asterix IV. Upon its completion in late 1999,
the PALS facility will be capable of providing single-
or multiple-pulse irradiation with a variable pulse duration
ranging from 100 to 500 ps. Wavelengths available will
be 1.315 μm, 658 nm, and 438 nm. The system will provide
one main beam with energy up to 1200 J and two smaller
auxiliary beams with a combined energy of up to 100 J.
A wide variety of geometries and variable pulse timings
is available. We assess PALS' potential for investigating
the physics of laser plasmas in inertial confinement fusion,
the development and applications of X-ray lasers, X-ray
spectroscopy, and radiation transport, using multiple-pulse
and extended beam capability.
