Abstract:
1. A system for spatially addressing generation of a non-linear interaction light, said non-linear interaction light being generated by an interaction between first and second light pulses having respectively first and second spectra, said first and second discrete spectra including respectively first and a second wavelengths, said first and second wavelengths differing from each other, said system comprising: a first light source for generating said first light pulse in response to receiving a first source trigger and a second light source for generating said second light pulse in response to receiving a second source trigger; a first optical waveguide having a first waveguide length and a second optical waveguide having a second waveguide length, said first optical waveguide transmitting light having said first and second wavelengths respectively at first waveguide first and second wavelength velocities and said second optical waveguide transmitting light having said first and second wavelengths respectively at second waveguide first and second wavelength velocities, said first and second waveguide second wavelength velocities being respectively larger than said first and second waveguide first wavelength velocities; an optical coupling element optically coupled to said first and second light sources and to said first and second optical waveguides for collecting said first and second light pulses from said first and second light sources and splitting said first and second light pulses so that a first portion of said first and second light pulses is transmitted to said first optical waveguide and a second portion of said first and second light pulses is transmitted to said second optical waveguide; a first interaction material optically coupled to said first optical waveguide opposed to said optical coupling element, said first interaction material producing said non-linear interaction light when illuminated substantially simultaneously at said first and second wavelengths; a second interaction material optically coupled to said second optical waveguide opposed to said optical coupling element, said second interaction material producing said non-linear interaction light when illuminated substantially simultaneously at said first and second wavelengths; and a triggering element for generating said first and second source triggers, said triggering element being operatively coupled to said first and second light sources for providing respectively said first and second source triggers thereto, a trigger delay between said first and second source triggers being selectively adjustable such that said second light pulse is produced at one of a first predetermined delay and a second predetermined delay after said first light pulse to cause said first and second light pulses to be separated from each other respectively by first and second propagation time differentials when arriving at said first and second light guiding elements; wherein said first propagation time differential is equal to said first waveguide length divided by said first waveguide first wavelength velocity, from which is subtracted said first waveguide length divided by said first waveguide second wavelength velocity, and said second propagation time differential is equal to said second waveguide length divided by said second waveguide first wavelength velocity, from which is subtracted said second waveguide length divided by said second waveguide second wavelength velocity; whereby, when said first and second light pulses are separated from each other by said first predetermined delay, said non-linear interaction light is produced in said first interaction material, and when said first and second light pulses are separated from each other by said second predetermined delay, said non-linear interaction light is produced in said second interaction material.
