Standing Waves in a Cavity

Standing Waves in a Cavity

A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Area of Science:

Plasma physics
Laser-plasma interactions
Particle acceleration

Background:

Laser-driven acceleration offers a path to compact, high-energy particle sources.
Plasma waveguides are crucial for guiding high-intensity lasers over long distances.
Previous methods for creating plasma waveguides lacked precise control over properties.

Purpose of the Study:

To demonstrate a new, highly tunable technique for generating meter-scale low-density plasma waveguides.
To enable laser-driven electron acceleration to tens of GeV in a single stage.
To provide wide control over plasma waveguide density, depth, and mode confinement.

Main Methods:

Utilizing two time-separated Bessel beam pulses for optical field ionization in hydrogen gas.
The first J0 beam pulse creates the waveguide core.
A delayed second pulse (J8 or J16 beam) generates the waveguide cladding, allowing tunable control.

Main Results:

Successfully generated meter-scale plasma waveguides with tunable properties.
Demonstrated guiding of intense laser pulses over hundreds of Rayleigh lengths.
Achieved on-axis plasma densities as low as N_{e0}∼5×10^{16} cm^{-3}.

Conclusions:

The demonstrated technique offers precise control over plasma waveguide parameters.
This method is a significant step towards compact, high-energy laser-driven electron accelerators.
The ability to create low-density waveguides is key for efficient acceleration stages.
