Abstract
The subject invention relates to beam control prisms and the use of a beam control prism to modify the beam properties of light emitted from an edge emitting diode laser. The subject invention can utilize a beam control prism placed next to a diode laser bar. The subject beam control prism can have, for example, a curved surface and/or a high reflective coated surface for a diode laser wavelength. The curved surface can collimate the fast axis divergence and the mirror surface can change the beam direction. The subject curved surface beam control prisms can incorporate one or more features, such as parabolic reflecting surface, elliptical exit surface with flat reflecting surface, and a hyperbolic entrance surface with flat reflecting surface.
