Abstract

Atmospheric CO2 absorption at the line center of P(20) CO2 laser radiation has been calculated at different altitudes by using the relationship 1-exp(-l1l2kdl). In this calculation, the absorption caused by water vapor has not been included. The line strength and the half-width at 295 K and 1 atm pressure used are 5.09 × 10−4 cm−2 atm−1 and 0.07 cm−1 atm−1, respectively.
