01870 IUPAC Gold Book - dye laser 10.1351/goldbook.D01870 D01870 current 1 A CW or pulsed source of coherent radiation in which the active medium is usually a solution of a fluorescent organic molecule (the dye) pumped with a suitable pump laser or with a flash lamp. These lasers can be tuned over a large part of the fluorescence band of the dye. active medium https://goldbook.iupac.org/terms/view/A00106 coherent radiation https://goldbook.iupac.org/terms/view/C01130 fluorescence https://goldbook.iupac.org/terms/view/F02453 lamp https://goldbook.iupac.org/terms/view/L03447 laser https://goldbook.iupac.org/terms/view/L03459 PAC, 1996, 68, 2223.
