Cubic phase modulation of a gaussian beam

  1. Nov 23, 2014 #1
    Hi all,

    I'm reading a paper on light sheet microscopy, i won't go into detail here but they are generating the light sheet by use of an Airy beam. They are using a term i don't understand when describing how the airy beam is generated. Quote "An Airy beam can be generated through the Fourier transformation of a cubic phase imposed upon an incident Gaussian beam". What is a cubic phase in this context? Apparently this phase modulation can be induced with a spatial light modulator.

    A layman's explanation would be beneficial, as i'm a biologist not a physicist.

    Thanks!
