A prismatic device for reforming the cross section of the beam emitted along a semiconductor laser bar stripe by deflecting successive segments of the emitted beam in directions making acute angles with the longitudinal axis of the emitted beam and redirecting the deflected beam segments through layers of glass into an array of parallel beam segments.

Diode beam transformation

A group of diode lasers emitting beams at a first wavelength is positioned above and below a stack of laser diodes emitting beams at a second wavelength. The first wavelength beams are directed to a dichroic portion of a compound prism and are reflected outwardly. The second wavelength beams are directed to the opposite surface of the dichroic portion but pass through without reflection and so are directed into substantially the same outward plane as the first wavelength beams. The compound prism combines beams of two different wavelengths to achieve a greater power density in the given plane than can be obtained with beams of either wavelength alone. A second stack of dual wavelength laser beams may be concentrated with a second compound prism and the two stacks of laser beams may be combined using an array of interleaved, laterally reversed, identical, angular plates of refractive material so as to alternately overcome the lateral displacement of the beams from the laterally separated stacks of laser diodes.
