Abstract
A unidirectional light amplifier is described wherein laser light is utilized to create an anisotropic medium in which light is fully amplified in only one direction and fully absorbed in the opposite direction. It is analogous to the way in which a junction diode conducts electrical current more easily in one direction than in the other direction.
