Mutually guided light and particle beam propagation

Area of Science:

• Physics
• Optics
• Plasma Physics

Background:

• Atomic and molecular polarizability generate optical forces.
• These forces can trap particles and guide light beams.
• This interaction may enable self-guided propagation of laser and particle beams.

Purpose of the Study:

• Investigate mutual interactions between expanding particle beams and diffracting light beams.
• Analyze the nonlinear coupling between particles and photons.
• Explore applications in space propulsion.

Main Methods:

• Axisymmetric particle-light coupled simulation.
• Analysis of nonlinear coupling parameters (particle beam radius, density, velocity, temperature, polarizability; light beam waist, frequency, intensity).

Main Results:

• Maximum propagation distance achieved with optimized single-mode waveguiding.
• Nonlinear coupling is dependent on multiple physical parameters.
• Demonstrated feasibility of coupled beam propagation.

Conclusions:

• Optimized waveguiding is crucial for maximizing beam propagation distance.
• The study provides insights into particle-light interactions.
• Coupled beam propagation shows promise for space propulsion systems.
