Abstract :
Heterodyne measurements of the intrapulse frequency behavior of an injection mode selected TEA CO2laser 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.
