Atmospheric Absorption at the Line Center of P(20) CO_2 Laser Radiation

Abstract

Atmospheric CO(2) absorption at the line center of P(20) CO(2) laser radiation has been calculated at different altitudes by using the relationship 1 - exp(-integral(l)(2)(l)(1) kdl). 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 x 10(-4) cm(-2) atm -(1) and 0.07 cm -(1) atm (-1), respectively.
