دومین نسل هارمونیک پرتو گاوسی (اپتیک موج) – کامسول

It is possible to generate harmonics that are multiples of the frequency of laser light by using nonlinear optical materials. This model demonstrates second harmonic generation using transient wave simulation and nonlinear material properties. A YAG (lambda=1.06 micron) laser beam is focused on a nonlinear crystal so that the waist of the beam is inside the crystal.
