Abstract : The patent concerns a high speed multipositional, laser beam deflection system of unique concept which employs a source of laser energy, preferably of determinable narrow-band spectral character. The source of laser energy includes means for selectively changing the spectral character of the laser energy, preferably by an appropriate effective technique which provides an extremely narrow-band spectral region in the selected wavelength range and is continuously tunable throughout a relatively broad range. The selected narrow-band region is intercepted and expanded into a collimated beam of desired dimension. The beam can be controlled by an acoustooptic filter, diffraction grating or prism. This works well with liquid dye lasers.
