Abstract:
Laser light modes are beams in whose cross-section the complex amplitude is described by eigenfunctions of theoperator of light propagation in the waveguide medium. The fundamental properties of modes are their orthogonalityand their ability to retain their structure during propagation for example in a lenslike medium or in free space. Developed diffractive optical elements (DOEs) of MODAN-type open up new promising potentialities of solving the tasks ofgeneration, transformation, superposition of different laser modes and their combinations. Now we present new resultsobtained by synthesis and investigation of beams consisting of more than one two-dimensional Gaussian laser modeswith the same value of propagation constant - multimode dispersionless beams.
