  • Laser Projection System with Potassium Gadolinium Tungstate
    Publication number: 20150277136
    Abstract: An apparatus and method for enhancing light using stimulated Raman scattering in a potassium gadolinium tungstate (KGW) crystal. The stimulated Raman scattering is utilized to add wavelength diversity for reduced speckle and to change the color of the light to a more desirable combination of wavelengths. Digital projection is one application that may benefit from lower speckle and shifted color. Color-based stereoscopic projection is enabled by the addition of stimulated Raman bands at specific wavelengths.
