Abstract
An optically-pumped laser having a small-molecule thin organic film of DCM doped Alq.sub.3. Carrier transport properties of the small-molecule organic materials, combined with a low lasing threshold provide a new generation of diode lasers employing organic thin films. An electrically-pumped variant is also described.
Claims79
A laser comprising:
- a substrate;
- and
- a layer of thin film organic material arranged on the substrate wherein
- the organic material has an index of refraction greater than an index of refraction of the substrate, and
- the organic material lases when pumped to thereby produce laser light.
2 more elements
A laser comprising:
- a substrate;
- a first electrode arranged on the substrate;
- a first cladding layer arranged on the first electrode;
- an active organic layer arranged on the first cladding layer;
- a second cladding layer arranged on the active organic layer;
- and
- a second electrode arranged on the second cladding layer.
4 more elements
A laser comprising:
- a substrate;
- a layer of thin film organic material arranged on the substrate;
- and
- a light source for optically pumping said organic material;
- whereby said organic material lases when pumped with said light source.
2 more elements
A laser comprising
- a substrate;
- and
- a layer of thin film organic material arranged on the substrate,
- wherein the organic material has an index of refraction greater than an index of refraction of the substrate, and the organic material lases when pumped to thereby produce laser light;
- and
- wherein the layer of organic material includes two reflective facets substantially parallel to each other, thereby forming an optical resonator.
