Optical Parametric Generation

Sum frequency generation: Parametric generation: Phase matching condition for collinear beams:

  • Angle tuning for phase matching
  • Extremely low signal and idler intensities
  • Type I/ Type II phase matching,

depending on NLO material

  • IR generation and single photon creation
