Scaling laws for the intrapulse frequency stability of an injection mode selected TEA CO<inf>2</inf>laser

Abstract

Heterodyne measurements of the intrapulse frequency behavior of an injection mode selected TEA CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> laser are presented. The frequency rose as the square of time at a rate varying linearly with energy and strongly dependent on spot size. These results are in accordance with a laser induced medium perturbative (LIMP) model, which allows the chirp in any TEA laser system to be predicted.
