Laser dye

 ( Laser Gain Media ) 

A Laser dye is a dye used as laser medium in a dye laser.F. P. Schäfer (Ed.), Dye Lasers, 3rd Ed. (Springer-Verlag, Berlin, 1990).F. J. Duarte and L. W. Hillman (Eds.), Dye Laser Principles (Academic, New York, 1990).

Laser dyes include the coumarins and the rhodamines. Coumarin dyes emit in the green region of the spectrum, whereas rhodamine dyes are used for emission in the yellow-red. The color emitted by the laser dyes depend upon the surrounding medium i.e.the medium in which they are dissolved. However, there are dozens of laser dyes that can be used to span continuously the emission spectrum from the near ultraviolet to the near infrared.F. J. Duarte, Tunable Laser Optics (Elsevier-Academic, New York, 2003) Appendix of Laser Dyes (includes more than 50 laser dyes)A. J. C. Kuehne and M. C. Gather, Organic Lasers: Recent Developments on Materials, Device Geometries, and Fabrication Techniques, Chem. Rev. 116, 12823-12864 (2016).

Laser dyes are also used to dope solid-state matrices, such as poly(methyl methacrylate) (PMMA), and Ormosil, to provide gain media for solid state dye lasers.
