Analysis of the propagation dynamics and Gouy phase of Airy beams using the fast Fresnel transform algorithm.

There is great interest in Airy beams because they appear to propagate in a curved path. These beams are usually generated by inserting a cubic phase mask onto the input plane of a Fourier transform system. Here, we utilize a fast Fresnel diffraction algorithm to easily derive both the propagation dynamics and the Gouy phase shift for these beams. The… CONTINUE READING
