Multimode

A multimode beam consists of a sum of any number of other beams. The sum may be coherent or incoherent, and several options exist for scaling, randomizing, and altering the phase of the individual components of the beam. The multimode beam sum is defined in a user defined text file. The file must end in the extension ZMM (for Zemax Multi Mode).

All ZMM Files must be placed in the <pop> folder (for details, search the Help Files for "Folders")

The ZMM file uses a simple command syntax that defines the multimode beam. The "master" beam is initially set to zero amplitude over the entire beam. The individual component beams are generated in the sequence defined in the ZMM file. Each beam as defined in the ZMM file is then summed either coherently or incoherently with the master beam. The sum mode, either coherent or incoherent, is controlled by the COHERENT and INCOHERENT commands. The default sum mode is COHERENT. All of the available ZMM commands are described below.
