Study of infrared and visible gas lasers

Several topics are summarized in the areas of laser studies of velocity-dependent collision cross sections continuously-tunable high-pressure CO2 lasers, multifrequency CO2 lasers, vibrational energy transfer in summetric top molecules, visible laser-induced chemical reactions, coherent pulse propagation and population inversion using adiabatic rapid passage, high-pressure CO2 capillary lasers, study of molecular helium, a stacked Blumlein N2 laser, excimer lasers, water vapor spectroscopy using a tunable SFR laser, two photon spectroscopy in NO, anomalous Zeeman in CO2 and N2O, and hyperfine structure in N2O.
