Nonlinear Optical Processes
Nonlinear optical processes occur when high-intensity ultrafast laser pulses interact with matter, causing a nonlinear material response that gives rise to phenomena such as frequency conversion (e.g., harmonic generation, optical parametric amplification), self-phase modulation, and high-order harmonic generation—forming the physical foundation for attosecond science, ultrafast spectroscopy, and precision microfabrication.
