Abstract

The halfwidth of the P(16) CO₂ laser transition has been measured over a temperature range from 373 to 620 K at pressures varying from 20 to 100 Torr. A Voigt profile line shape was fitted to the experimental absorption coefficient to determine the variation of halfwidth with temperature. The pressure broadened halfwidth varied as T^−0.56 over this temperature range.
