Abstract
We report 2-Hz operation of a single-pass 109-nm laser with a small-signal gain of exp 33 and a saturated output energy of 1 μJ. The laser is based on an oblique-incidence, laser-produced-plasma pumping geometry and requires only 500 mJ of 1064-nm energy in a 0.5-nsec pump pulse. We use the laser to produce a two-slit interference pattern and demonstrate a focusable intensity of greater than 109 W/cm2.
