Patent ID: 6845114

Claim:
A vertical cavity organic laser device having a substantially low threshold for optical excitation, wherein the optical excitation occurs below 0.1 W/cm 2 power density, comprising: a) an organic laser cavity and having a substantially low threshold for optical excitation including: a1) a bottom dielectric stack for receiving and transmitting pump beam light and being reflective to laser light over a predetermined range of wavelengths; a2) an organic active region for receiving transmitted pump beam light from the first dielectric stack and for emitting the laser light; and a3) a top dielectric stack for reflecting transmitted pump beam light and the laser light from the organic active region back into the organic active region, wherein a combination of the bottom and the top dielectric stacks and the organic active region produces the laser light; b) an external pump beam light source for optically pumping light to the organic laser cavity having a substantially low threshold for optical excitation; and c) a positioner for holding and/or adjusting the organic laser cavity having a substantially low threshold for optical excitation in a spaced relationship to the external pump beam light source.
