An electro-optical system includes a plurality of electromagnetic gain
media having a corresponding plurality of apertures. The apertures are
disposed in a predetermined spatial distribution. The system further
includes at least one refracting surface disposed to intercept energy
from the plurality of apertures and a reflecting surface to direct
portions of the intercepted energy back through the at least one
refracting surface and back toward the plurality of apertures. The return
energy is distributed about the plurality of apertures.
