Figure 1: Line broadening in a CO_(2) laser as a function of gas pressure. The laser operates at 943.3cm^(-1). The lifetime of the upper lasing level is 1 imes 10^(-5)s and the lifetime of the lower level is 20mu s.
(c) Estimate the operating temperature of the CO_(2) gas, given that the molar inass of O and C are 15.99gmol^(-1) and 12gmol^(-1), respectively.
