New Materials for Flash-Pumped Organic Lasers

Two compounds derived from 2-hydroxyquinoline were found to lase in the violet region of the spectrum when pumped by a flashlamp. Two aminocoumarin derivatives, under the same conditions, lased intensely in the range from 440 to 480 nm at a wavelength that depended on the addition of acid.
