Patent Number Title Of Patent Date Issued
7667391 Electrically excited organic light-emitting diodes with spatial and spectral coherence February 23, 2010
A light-emitting device, comprising: a multi-layer stack of materials supported on an optically transparent support member, a first spatial filter, and a second spatial filter spaced from the first spatial filter. The multi-layer stack including at least one organic light-emitting la
7065115 External cavity organic laser June 20, 2006
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
6903824 Laser sensitometer June 7, 2005
An optical apparatus. More particularly, a laser sensitometer. The apparatus comprises: a polarized light source adapted to provide a Gaussian beam of light directed along an optical axis; a rotatable polarizer disposed in the optical axis adapted to vary an intensity of the beam of
6888862 Dye-doped polymer nanoparticle gain medium May 3, 2005
A gain medium for producing a light emission in a laser. The gain medium comprises a dye-doped polymer nanoparticle matrix having an absolute value of dn/dT less than an absolute value of dn/dT of its dye-doped polymer matrix.
6236461 Laser sensitometer using multiple-prism beam expansion and a polarizer May 22, 2001
An electro-optical apparatus particularly suitable for exposing a sample of light sensitive material to provide a graded series of exposures of different intensity levels. The apparatus includes a light source, beam shaping optics, and a rotatable polarizer. The light source provides a
5255069 Electro-optical interferometric microdensitometer system October 19, 1993
There is disclosed an interferometric system including electro-optical apparatus and method for examining and characterizing ultra fine details of various specimens such as a piece of photographic film. The method includes illuminating a specimen with a thin wide substantially pure G
5181222 Laser oscillator January 19, 1993
Laser apparatus is described in which the optical cavity of a laser oscillator is specially provided with a polarizing device which has on its outer face a partially reflecting coating (such as a thin partially reflecting layer of low-loss dielectric material). The polarizing device
4891817 Pulsed dye laser apparatus for high PRF operation January 2, 1990
Laser apparatus is disclosed which comprises a compact pulsed dye laser for high pulse repetition frequency operation. The pulsed dye laser includes a resonator cell having a passageway through which dye solution is circulated and a pump laser for optically pumping the resonator. In orde
4822150 Optical device for rotating the polarization of a light beam April 18, 1989
An optical device is disclosed for rotating the polarization of a light beam, in particular a laser beam. In one embodiment of the invention, the device comprises a prism which is adapted to rotate the polarization of a linearly-polarized beam of radiation by 90.degree. and to change the
