A Matrix Approach to a Propagation Code.

Abstract

A transfer matrix for CO2 laser beams with an assumed gaussian intensity distribution is developed that includes parameters for absorption, turbulence, and thermal blooming. Calculated parameters are an effective beam radius (1/sq e point) and an on-axis intensity. For moderate power levels, results are consistent with the computer code COMBO. The blooming model predicts results worse than those predicted by COMBO for high power levels. (Author)
