We experimentally investigate propagation of laser beams with different intensity profiles in highly scattering media. We generate transverse laser amplitude profiles with Gaussian, Bessel and Airy function envelopes. We then propagate these beams through optical phantoms formed with variable density intralipid solutions. At the sample exit, we compare change in maximum intensities, as well as beam...
Shaping laser beams has been a fascinating topic in optic studies lately, because they exhibit intriguing characteristics and have potential applications. One of the most commonly used profiles is the Bessel beams. These beams, which are first shown by Durnin and others, are called also diffraction-free beams [1]. They have much long length of focus and their profiles do not change in free space propagation...
