A conically shaped pumping geometry can produce an efficient burst of laser radiation, without the need for an optical cavity, by restricting amplified spontaneous emission losses to a small region near the apex of the cone. Requirements on the active medium and on the size and intensity of the pumping source to make such a burst laser are derived. We calculate that a 15-mJ pulse of energy at 37.2 nm at an efficiency of 0.15% can be extracted from sodium vapor photoionized with radiation from a 1.06-..mu..m-laser-produced plasma using this pumping geometry.
