Abstract
A thin-film organic laser, that includes: a substrate; a bottom mirror provided on the substrate; at least one active region deposited on the bottom mirror, wherein the at least one active region includes organic gain material; an external mirror provided at a predetermined distance from the at least one active region such that the bottom mirror combined with the external mirror forms a laser resonator; and an optical pumping means for exciting the organic gain material to produce a laser beam with a wavelength λ and at least one lateral laser mode in the laser resonator and an output of laser light.
Claims23
A thin-film organic laser, comprising:
- a) a substrate;
- b) a bottom mirror provided on the substrate;
- c) at least one active region deposited on the bottom mirror, wherein the at least one active region includes organic gain material, wherein an organic active region is provided that includes one or more periodic gain regions aligned with antinodes of a light source's standing wave electromagnetic field, and organic spacer layers disposed on either side of the periodic gain regions;
- d) an external mirror provided at a predetermined distance from the at least one active region such that the bottom mirror combined with the external mirror forms a laser resonator;
- and
- e) an optical pumping means for exciting the organic gain material to produce a laser beam with a wavelength λ and at least one lateral laser mode in the laser resonator and an output of laser light.
