Organic laser

Organic lasers are inherently tunable and when configured as optimized multiple-prism grating laser oscillators can yield efficient single-transverse mode, and single-longitudinal-mode, emission with laser linewidths as narrow as 350 MHz (approximately 0.0004 nm at a wavelength of 590 nm), in the high-power pulsed regime.

[7] DDO and DDPN gain media are subsets of a larger class of organic-inorganic hybrid materials used as laser matrices.

[8][9] Other types of solid-state organic lasers include the organic semiconductor lasers that use conjugated polymers as gain media.

[10][11][12][13] These semiconductor materials can also be configured as "neat films.

"[14] 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.
