Patent ID: 6963594

Claim:
An organic laser cavity device, comprising: a) a first dielectric stack for receiving and transmitting pumped beam light and being reflective to laser light over a predetermined range of wavelengths and having a substantially low threshold for optical excitation, below 0.1 W/cm 2 power density; b) an organic active region, including one or more periodic gain regions and organic spacer layers disposed on either side of the periodic gain region and arranged so that the periodic gain regions are aligned with antinodes of the organic laser cavity device's standing wave electromagnetic field, and being in proximate contact with the first dielectric stack, for receiving the transmitted pumped beam light and the laser light from the first dielectric stack, and emitting the laser light; c) a second dielectric stack, in proximate contact with the organic active region and spaced from the first dielectric stack, for reflecting the transmitted pumped beam light and the laser light from the organic active region back into the organic active region, wherein a combination of the first and the second dielectric stacks and the organic active region outputs the laser light; and d) an external self-contained non-electrical photon source of the pumped beam light optimized for coupling with the organic laser cavity device for optical excitation at the substantially low threshold, wherein said optimization is based on providing uniform illumination.
