摘要	A color mixing system is proposed for use in an optical-fiber laser-diode assembly comprising at least two semiconductor laser diodes, optical fiber light input and output couples, a system of spatial superposition of laser beams of different wavelength with at least one semi-transparent mirror, and a system for electronic control of light power in monochromatic light components to be mixed. The electronic control system makes it possible to produce a plurality of different colors. The basic colors, i.e., blue, green, and red, are produced by respective laser diode assemblies provided with means for adjusting output light power on each individual assembly. The electronic system contains a microprocessor connected to a pulse width modulation unit capable of modulating the duration and shape of the light pulse emitted from the laser diode. This allows for selecting a required ratio of energetic brightnesses of light beams produced by individual laser diode assemblies. The electronic system contains a microprocessor connected to a pulse width modulation unit capable of modulating the duration of the light pulse emitted from the laser diode for controlling chromaticity of the color and to a current source for controlling the luminescence, i.e., the light power. The aforementioned control of chromaticity and light power is carried out simultaneously in real time with reproduction of perfect colors based on the use of single-mode pure stabilized and frequency double wavelengths with narrow linewidths of the light spectra.
