Area of Science:

Optics and Photonics
Beam Propagation Physics

Background:

Diffraction-free beams, such as Bessel beams, are valuable for applications requiring stable propagation.
Light absorption in media typically attenuates beam intensity, limiting propagation distance.

Purpose of the Study:

To investigate the propagation characteristics of Bessel beams generated by phase-engineered axicons in lossy media.
To demonstrate the potential for maintaining beam intensity and the quasi-diffraction-free property under absorption.

Main Methods:

Phase engineering of an axicon's transmission function to generate Bessel beams.
Theoretical analysis and simulation of beam propagation in a medium obeying Beer's absorption law.

Main Results:

Phase-engineered axicons produce Bessel beams with exponentially growing on-axis intensity in lossless media.

In lossy media, these beams propagate with nearly constant intensity, preserving their quasi-diffraction-free nature.

Conclusions:

The proposed optical element design enables Bessel beam propagation with sustained intensity in absorbing environments.
This overcomes limitations of light absorption, opening avenues for applications in atmospheric propagation, biomedicine, and advanced illumination systems.
