Second Harmonic Generation of a Gaussian Beam

Application ID: 956


Laser systems are an important application area in modern electronics. With nonlinear materials it is possible to generate harmonics that are a multiple of the frequency of the laser light.

This model shows how a second harmonic generation can be set up as a transient wave simulation, using nonlinear material properties. A YAG (lambda=1.06 microm.) laser beam is focused on a nonlinear crystal, so that the waist of the beam is inside the crystal.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
