Paper Abstract

We report the operation of a short pulse photolytic iodine laser (PIL) using an unstable resonator under long-pulse and injection seeded operation. The laser is designed as a surrogate source to replicate the output from a q-switched chemical oxygen iodine laser (COIL). Under long pulse conditions the single shot laser produces up to 10 Joules in a 3 microsecond(s) pulse. When seeded with the output from a narrow pulse (10 ns) broadband KTP Optical Parametric Oscillator (OPO), the temporal output is composed of a train of 10 ns pulses separated by the round trip time of the cavity. The enhanced peak power in the individual pulses is more attractive for subsequent efficient Raman conversion. A description of the laser performance with the unstable resonator and with seeding is presented.
