Organic lasers use an
organic
Organic may refer to:
* Organic, of or relating to an organism, a living entity
* Organic, of or relating to an anatomical organ
Chemistry
* Organic matter, matter that has come from a once-living organism, is capable of decay or is the product ...
(carbon based) material as the gain medium. The first organic laser was the liquid
dye laser. These lasers use
laser dye solutions as their gain media.
Organic lasers are inherently tunable and when configured as optimized
multiple-prism grating laser oscillators Multiple-prism grating laser oscillators,F. J. Duarte, Narrow-linewidth pulsed dye laser oscillators, in ''Dye Laser Principles'' (Academic, New York, 1990) Chapter 4. or MPG laser oscillators, use multiple-prism beam expansion to illuminate a diff ...
can yield efficient single-transverse mode, and single-longitudinal-mode, emission with
laser linewidth
Laser linewidth is the spectral linewidth of a laser beam.
Two of the most distinctive characteristics of laser emission are spatial coherence and spectral coherence. While spatial coherence is related to the beam divergence of the laser, spect ...
s as narrow as 350 MHz (approximately 0.0004 nm at a wavelength of 590 nm), in the high-power pulsed regime.
Solid-state dye lasers
Solid-state dye lasers Solid-state dye lasers (SSDL) were introduced in 1967 by Soffer and McFarland. In these solid-state lasers, the gain medium is a laser dye-doped organic matrix such as poly(methyl methacrylate) (PMMA), rather than a liquid solution of the dye. An ...

ormosil Ormosil is a shorthand phrase for ''organically modified silica'' or ''organically modified silicate''. In general, ormosils are produced by adding silane to silica-derived gel during the sol-gel process. They are engineered materials that show gr ...
(DDO), and laser dye-doped polymer-nanoparticle (DDPN) matrices.
DDO and DDPN gain media are subsets of a larger class of organic-inorganic hybrid materials used as laser matrices.
Organic semiconductor laser
Other types of solid-state organic lasers include the organic semiconductor lasers that use
conjugated polymers as gain media. These semiconductor materials can also be configured as "neat films."
Coherent emission, characterized via high-visibility double-slit interferograms (''V'' ~ 0.9) and near diffraction-limited beam divergence, has been reported from electrically-pumped coumarin dye-doped tandem
OLED devices.
Distributed feedback laser
Organic lasers are also available in
distributed feedback configurations and distributed feedback waveguides.
