- Complete modal decomposition for optical fibers using CGH-based correlation filtersThomas Kaiser
Institute of Applied Physics, Friedrich Schiller University Jena, D 07743 Jena
Opt Express 17:9347-56. 2009..Advantages of this approach are its mathematical uniqueness and its experimental simplicity. The method constitutes a promising technique for real-time beam characterization, even for singular beam profiles...
- Fast M2 measurement for fiber beams based on modal analysisDaniel Flamm
Institute of Applied Optics, Friedrich Schiller University Jena, Fröbelstieg 1, D 07743 Jena, Germany
Appl Opt 51:987-93. 2012..With this information at hand, we are able to simulate the free-space propagation of the beam and to perform a virtual caustic measurement. Associated beam propagation ratios M(2) accurately agree with ISO-standard measurements...
