H_2 Lyman and Werner Bands Laser Theory

Abstract

The laser power densities for the Lyman and Werner bands are calculated with a complete rotational analysis. For the Lyman band, P(3) and P(1) are favored and are stronger than Werner Q(1) and P(3) transitions even though the latter are favored in excitation. The transitions from Lyman levels to the lower ground state vibrational levels, where most of the strong Werner transitions terminate, reduce the net inversion density for the Werner band.
