title: Cascade population mechanism in nitrogen lasers.
abstract: The way in which a cascade mechanism from the C3Pi(u) state affects the population of the v = 0 level of the B3Pi(g) state in a N2 laser is studied. The spectra of the 0-1 IR laser band are fit by using simple theoretical calculations that account for the population of the three laser levels involved, C3Pi(u) B3Pi(g) and A3Sigma(u)+ and two excitation mechanisms, direct electron impact and cascade. The inhibition of the 0-0 UV laser band showed a strong influence on the 0-1 IR laser band output.
