A method and apparatus for modulating light, wherein a light source provides light of a certain wavelength to be modulated. A light modulating device is placed in the optical path of the light source. The resulting optical pulses transmitted through the light modulating device are converted from the original wavelength to a lower wavelength by a frequency converting device.
