<p>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.</p> |
