One Meter KrF Laser System
Abstract
This interim technical report covers DARPA-sponsored research directed towards high power rare gas-halide lasers. The key issues being addressed are: kinetics leading to laser medium gain and absorption, laser energy extraction, upper and lower laser state kinetics, intrinsic laser efficiency, specfic energy, and energy scaling. By operating at elevated temperatures and e-beam pumped XeF laser intrinsic efficiency of 5.5% was obtained at a specific pulse energy of 5 J/1. The increase in efficiency is attributed to improved energy extraction from the XeF* (B) vibrational manifold and to decreased lifetime of the XeF ground state. Detailed comparisons were made between KrF laser experiments and model calculations. Excellent agreement was obtained. The comparison also suggests the importance of KrF* vibrational rotational relaxation and B and C state mixing on laser performance at pump intensities exceeding 1,000,000 W/cu cm.
