Second-harmonic generation (SHG, also called frequency doubling) is a nonlinear optical process in which two photons with the same frequency interact with a nonlinear material, are "combined", and generate a new photon with twice the energy of the initial photons (equivalently, twice the frequency and half the ...
High harmonic generation (HHG) is a non-linear process during which a target is illuminated by an intense laser pulse. Under such conditions, the sample will ...
Third-harmonic generation (THG) can be performed either directly by a THG process or as a two-step process involving two sequential harmonic generation steps.
A common approach is to use two LBO (lithium triborate) crystals, or an LBO and an BBO crystal, the first being phase-matched for second-harmonic generation ...
Harmonic generation is a nonlinear optical process in which n photons with the same frequency interact with a nonlinear material, are "combined", and generate ...
Harmonic generation is a non-linear optical process in which photons of intense incoming laser radiation interact with a non-linear material and radiation with ...
High harmonic generation is the phenomenon that very high harmonics of an intense input laser beam are generated in a gas. It can lead to soft or even hard ...
2019年9月19日 - The APE HarmoniXX product line is a series of frequency converters for harmonic generation for ultrafast lasers, covering SHG, THG, and FHG.
Third Harmonic Generation (THG) is a process whereby light is generated at a wavelength which is 1/3 of the pump wavelength, and it is achieved by a two ...
