The second harmonic generation is widely used to extend the choice of wavelengths generated by lasers. It is most efficient for pulsed lasers but also can be used ...

This can give rise to the phenomenon of frequency doubling, where an input (pump) wave generates another wave with twice the optical frequency (i.e., half the ...

Frequency doubling (or second-harmonic generation) is the phenomenon that an input wave in a nonlinear material can generate a wave with twice the optical ...

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 ...

Second Harmonic Generation (SHG) is a coherent optical process of radiation of dipoles in the material, dependent on the second term of the expansion of polarization. The dipoles are oscillated with the applied electric field of frequency w, and it radiates electric field of 2w as well as 1w.
