You can obtain a copy of the setup as a PDF to paste in your presentations with or without the beam. You have a request for ABCD. As long as it is within the ray matrix formalism, it is possible to accommodate your needs. Home Tutorials Beam propagation tutorial About. What is ABCD. Simple laser beam propagation calculations with ray matrices. We can see this because the effect of the propagation in the distance term would just be to add a distance d. This can be written as:. Conclusion: Looking at the above two cases, we can see that with a given change of the ABCD matrix, we can have the relation for the complex radius of curvature q:.

This ABCD Law relates the complex radius of curvature at the front and back reference planes of a system through a ray matrix. We can interpret the ABCD law as stating that the complex q parameter transforms in the same way as R in geometrical optics. This turns out to be a generally true statement for paraxial system and not just the two presented above.

The following list gives the ABCD matrices of frequently used optical elements. Air space with length d :. Example: combined matrix for free-space propagation length with distance d , followed by a lens with focal length f :. Some typical applications of the ABCD matrix algorithm are: It is often of interest how a laser beam propagates through some optical setup.

Both the geometric path of a ray and the evolution of the beam radius can be calculated. The changes of beam parameters within one complete round trip in a resonator can be described with an ABCD matrix. The transverse resonator modes can then be obtained from the matrix components.
