Interaction of a laser beam with the rotational lines of nitrogen in the wavelength region of 5700 A

Propagation of a dye laser beam of wavelength 5700 A through nitrogen is considered. Values of transmittance, averaged over intervals of 0.5 cm(-1), are obtained for absorber thicknesses of 0.1, 1, and 10 atm-cm, using the quasi-random model of molecular band absorption. From these values, intensities of the absorption lines in the first positive system of N(2) are simulated in the frequency interval of 17,540-17,548 cm(-1).
