Design of autofocusing beams based on accelerating beams
Summary
Autofocusing Airy-like beams were designed and studied in free space and turbulence. Beam trajectory influences energy concentration and turbulence resistance, with less curved paths showing better stability.
Area of Science:
- Optical physics
- Beam propagation
Background:
- Self-accelerating beams offer unique propagation dynamics.
- Airy-like beams exhibit non-diffracting and self-healing properties.
Purpose of the Study:
- To design and investigate autofocusing Airy-like beams.
- To analyze beam evolution in free space and turbulent environments.
- To understand the relationship between trajectory and beam characteristics.
Main Methods:
- Design of autofocusing Airy-like beams based on polynomial paths.
- Simulation of beam propagation in free space.
- Simulation of beam propagation through atmospheric turbulence models.
Main Results:
- Energy concentration near the focal plane correlates with the accelerating trajectory.
- Spot size in the focal plane is dependent on the acceleration path.
- Turbulence impact varies with beam curvature; shallow curves enhance resistance.
Conclusions:
- Autofocusing beam trajectory is critical for focal plane energy concentration.
- Beam path curvature dictates susceptibility to atmospheric turbulence.
- Optimizing trajectory offers a method to improve beam stability in turbulent media.
