The Petawatt High-Energy Laser for Heavy Ion
EXperiments (PHELIX) is a versatile laser facilitydelivering intense laser beams with
energies up to 1 kJoule or likewise powers > 500 TW. PHELIX is a flashlamp-pumped Nd:glass
system employing two frontends, a pre amplifier and a main amplifier. It was built in close
cooperation with Lawrence Livermore National Laboratory (LLNL)
in the US and the Commissariat à l'Energie Atomique (CEA) in France.

(Click on image for further information about the particular subsystems).
PHELIX serves three experimental areas: At the Z6 experimental area the worldwide
unique combination of intense laser radiation with heavy ion beams generated at GSI’s
accelarator facility (UNILAC)
opens the door for interesting experiments in the field of plasma physics, nuclear physics
and atomic physics. In addition, stand-alone experiments with intense laser beams can be
carried out for studies such as proton acceleration or X-ray laser generation. For moderate
beam intensities up to 10 TW an additional pulse compressor and target chamber is available.
For the generation of extreme laser intensities of > 1020 W/cm² the
chirped pulse amplification scheme
(CPA) is used where a
sub-picosecond laser pulse is stretched in time, amplified and recompressed afterwards.
High energy beams are generated by the nanosecond frontend, which delivers arbitrary pulse
shapes and pulse durations between 1 and 15 ns.
