Harmonic generation (HG, also called multiple harmonic generation) is a nonlinear optical process in which photons with the same frequency interact with a nonlinear material, are "combined", and generate a new photon with times the energy of the initial photons (equivalently, times the frequency and the wavelength divided by ). WebFeb 4, 2024 · For the Gaussian driving beam, harmonics are emitted every half period of the driving field, showing a periodicity of ∆t = T 0 /2 (where T 0 = 2π/ω 0 is the optical cycle associated to the central frequency of the driving field), which physically corresponds to the cadence of the ionization-rescattering mechanism leading to HHG. noun tough
