Abstract

This program has produced and demonstrated a small, compact and efficient flashlamp pumped titanium sapphire multiple pass oscillator, that uses a laser head in a close coupled configuration with a single linear flashlamp. This laser has produced up to 1.68 J/pulse in the free-running scheme at repetition rates of up to 10 Hz, with an efficiency of almost 1% at a wavelength of 790 nm. Wavelength tuning from 675 nm to 975 nm has been demonstrated, as having Q-switching, shortening the pulse duration to 20 ns, line narrowing to 2 angstrom and second harmonic generation. An oscillator amplifier configuration has also been demonstrated using a similar arrangement with three flashlamps and two laser rods, producing a beam with energy close to 4 J/pulse.
