Noncollinear sum-frequency generation (SFG)

Caption

Artistic rendering of noncollinear sum-frequency generation (SFG): two infrared pulses mix in a χ² crystal to produce three output pulses (green), with the central SFG pulse being the primary output of interest. A neural network, represented above, learns to model this coupled nonlinear mixing process.
