Short-Wavelength Infrared Line Emission in a Laser-Produced Oxygen Plasma

摘要

Reported are the first observations of infrared line emission from high-lying oxygen atom states produced in a laser generated oxygen plasma. Time resolved visible emission studies provide information on the temporal behavior of the atomic infrared emitting states. The relative populations of the observed O atom n=4 states are discussed in light of infrared oscillator strengths calculated according to the Coulomb approximation.
