Generation of coherent ultraviolet radiation in the 330 nm region by multiphoton excitation of sodium vapor
Abstract
The paper reports the observation of coherent UV emission at 330.2 + or - 0.5 nm when sodium vapor in a heatpipe is irradiated with a pulsed visible dye laser with output wavelength in the 570-595 nm region. It is found that intense UV emission can be produced from Na atoms as well as from Na2 molecules. The excitation functions and their dependence on vapor density and laser power density are presented and the mechanisms for producing the emission are discussed.
