ABSTRACT:
A system for thermally stimulating a laser emissive device comprises a thermal generating device, a photon emissive device that is capable of generating photons upon exposure to thermal energy, a laser emissive source, and an optical waveguide interposed between the photon emissive source and laser emissive source to direct photons to the laser emissive source to effect photon stimulation of the same. The waveguide may be in the form of a light pipe comprising the photon emissive material, which material is disposed within the thermal energy source. The photon emissive material is selected to produce a specific wavelength of photons that are collected within and directed through the optical waveguide to a laser rod. The photons routed to the laser rod stimulate a specific wavelength laser emission. If desired, the system can also be used with more than one target, e.g., more than one laser device, or a photovoltaic cell to produce electricity.
