Abstract

We created superpositions of two different TEM modes in focused beams. Such modes show relative dephasing along the beam axis due to Gouy's phase. This leads to interference effects and significant modifications of a beam's transverse intensity distribution near the beam focus. We investigate the features of the resulting field profiles.
