laser consists of discharge electrodes 50 mm long with a Blumlein line
in Kapton 125 microns thick and a low inductance coaxial spark gap.
This arrangement provides an instantaneous power of 440 kW in 500
picoseconds for only 5 cm long cavity.
The beam section is 3x2 mm. This cavity
was the amplifier stage in the MOPALITE lasers developed for the calibration of
the drifts chamber used at CERN in 1982 and developed by Arnold
