A two stage high energy iodine laser has been constructed using an existing oscillator stage that was modified so as to accept a Pockels cell and associated Brewster window stack for Q-switching. The output of the oscillator stage was then amplified by a second stage consisting of a 2.54 cm quartz lasing tube, 120 cm long and four flashlamps contained in an elliptical reflector. With 1180 Joules applied to the oscillator stage flashlamps, an output energy of 30 millijoules with a repeatability of two percent was achieved. Pulse duration measurements were detector limited. Estimates put the pulse duration at less than 100 ns. Applying 3580 J to the flashlamps of the amplifier stage and using the stated oscillator output resulted in an estimated output energy of 8.2 Joules with similar repeatability and pulse duration to that of the oscillator stage alone. For both stages the output beam profile was found to be gaussian.
