Abstract
An optical pumping system employs a first concave reflector for collecting solar energy and directing it toward a second concave reflector facing the first reflector in confocal relation therewith. The resulting collimated solar beam is redirected toward the first reflector and intercepted by a third reflector having planar walls that diverge toward the second reflector at equal acute angles to the common optical axis of the first and second reflectors; the third reflector causes the intercepted beam to uniformly excite a laser positioned along the optical axis between the diverging walls of the third reflector.
Claims5
In a system for optically pumping a laser with solar energy, a first concave reflector supported about an optical axis for collecting solar energy, a second concave reflector facing a front surface of the first reflector and disposed in confocal relation with the first reflector about the optical axis, a third reflector spaced from the second reflector in a direction toward the first reflector, the third reflector comprising a pair of planar walls diverging toward the second reflector at substantially equal acute angles to the optical axis, and means for supporting the laser on the optical axis between the diverging walls of the third reflector.
