Abstract
A positive column He–Se+ laser with cataphoretic vapor transport can be employed as a three-color laser which emits two blue lines at 460.4 and 464.9 nm, a green line at 522.8 nm, and two red lines at 644.4 and 649 nm, if a special resonator is used. For these three colors and for three individual tubes with different diameters of the fused silica capillary measurements were performed of the TEM00 mode spot size in the capillary and of the output mirror transmission by which a maximum output power is obtained. A laser with long lifetime has been made which emits 4-mW power per color.
