ABSTRACT:
A monolithic multi-color laser comprising a semiconductor laser formed on a substrate for lightwave generation. Means is provided for exciting the laser and means is provided on the substrate adjacent the laser to double the frequency of the lightwave emitted from the laser to produce output lightwaves having wavelengths in the photo-sensitive region of conventional silver halide photographic material. Further, an individually controllable frequency matched lightwave modulator is mounted on the substrate and is arranged to individually control the output lightwave in response to a data signal.
