APPARATUS FOR EFFICIENT, MORE UNIFORM HIGH POWER EXCITATION OF A DYE MEDIA OPTICAL AMPLIFIER

摘要

Apparatus for transversely irradiating a region equally from two directions using a single incident beam of substantially collimated radiation. The apparatus includes perpendicular reflective planes having a common edge and defining a corner region in which an irradiated region entirely within said corner region, said irradiated region being suitably positioned within said corner region such that said irradiated region does not intercept any ray of incident radiation from striking said common edge, said irradiated region receiving only radiation from two directions. Said irradiated region being directly irradiated from a first direction by incident radiation, and said irradiated region being also indirectly irradiated from a second direction opposite said first direction by incident radiation reflected from both of said planes.
