Although fluorescent ions in glass were studied extensively during the 1960s for possible lasing action, these studies were primarily restricted to narrow emission band, long decay time ions such as the trivalent rare earths. This restriction was necessitated by the limited power of the then available flashlamps. The development of powerful, short pulse flashlamps for dye layers in recent years has removed this constraint and now makes it feasible to consider broad-band emitters in glasses and crystals for lasing action. As opposed to the trivalent rare earths, which generally have their strongest fluorescent lines in the near IR, broad-band emitters offer the possibility of visible and near UV lasers. Tuning over wide frequency ranges is also a possibility. In this study, interest was primarily directed towards ions emitting in or near the spectral region between 0.5 micrometer and 1.0 micrometer.
