Multiple Phase Anomalies in Bessel Beam

The non-diverging feature of the Bessel-kind beam leads to multiple phase anomalies along the optical axis in contrary to the focused Gaussian beam. Here, we analyze the phase distributions using in a longitudinal-differential phase mode of a high-resolution interference microscope. The measured data are compared with rigorous simulations, showing an excellent agreement.
