Claims
- 1. An apparatus for driving solid state laser media by a remote nuclear-powered source comprising:
- a) a nuclear reaction chamber producing diffuse fluorescence in the visible to infrared range, the reaction chamber including an aperture containing a lens capable of collecting the diffuse fluorescence from the reaction chamber, and further wherein the reaction chamber has an interior surface coated with material which is reflective and transmissive to visible to near infrared light such that the diffuse fluorescence collected in the reaction chamber by the lens is in the absorption bands of the remote solid state laser;
- b) channeling means for channeling the fluorescence from the reaction chamber to the remote laser; the channeling means including a waveguide adjacent to the lens for channeling the collected fluorescence from the lens to the remotely located laser and,
- c) coupling means for coupling the fluorescence to the laser such that the fluorescence is absorbed into the laser and pumps the laser.
- 2. The apparatus of claim 1 wherein the waveguide is a radiation hardened fiber optic waveguide.
- 3. The apparatus of claim 2 wherein the reaction chamber has a cylindrical geometry having a relatively large length to radius ratio.
- 4. The apparatus of claim 3 wherein the fluorescence collected from the reaction chamber and transmitted through the waveguide is coupled to the remotely-located laser by a plurality of optic fibers mounted normal to the surface of a cylindrical sleeve which surrounds the laser, whereby fluorescence from the optic fibers is absorbed by the laser.
- 5. The apparatus of claim 4 wherein the laser is Nd:Glass.
