Interferometric Optics |
---|

Numerical calculations, near or far field, for the interference produced by the interaction of laser light with an array of

An additional application is the characterization of the emission transverse-mode structure in laser oscillators and/or laser resonators. In other words, the cavity and emission beam geometry can be optimized to achieve single-transverse-mode emission at maximum efficiency. This is a powerful design tool that saves time, resources, and effort in laser architecture and engineering.

Note: the interferometric calculations mentioned here are performed using equations derived from the application of Dirac's quantum notation to propagation in a given geometry. The principles of this approach are described in F. J. Duarte,
