Abstract
Kerr beam cleaning is very sensitive both to the incident angle and beam size. The last one defines the number of excited modes at the entrance of GRIN MMF that should be not too high and not too low. We have measured the output beam spectrum as a function of peak power and analyzed it together with the beam profile variation.File allegati a questo prodotto
