Experimental setup:
Ìîdan 1 generates the Gauss-Hermite mode (1,0), Ìîdan 2 - the Gauss-Hermite
mode (0,1), and Ìîdan 3 ànalyzes the beam modal composition.

Experimental setup:
Ìîdan 1 generates the Gauss-Hermite mode (1,0), Ìîdan 2 - the Gauss-Hermite mode (0,1), and Ìîdan 3 ànalyzes the beam modal composition.
Results of physical experiment:
à - the mode under detection is present in the specified channel,
b - the desired mode is absent in the beam,
c - both modes nder detection are present in the beam.
