Abstract

A single gun He-Cd⁺ laser utilizes a He-Cd mixture as a laser medium and oscillates at seven spectral lines of three primary colors emitted from excited Cd⁺ simultaneously. Because the powers at the three primary colors are balanced, the composite output beam appears white. Hence the name `white light laser'. White light lasers have various applicability in the fields of science and technology such as medical diagnostics and surgery, photochemistry and isotope separation as an energy source, and for color display, color holography, color printers as a light source. In this report, we present conclusive evidence about the population mechanisms to produce excited Cd ions, especially for the green laser lines.
