“…Due to formation of plasma channels, a number of applications based on this phenomenon have been growing rapidly during the past few years [6]. Based on the properties of plasma filaments, systems for laser-driven electron accelerator [7], terahertz radiation sources [8], triggering of high-voltage discharges in megavolt switches, lightning control in the storm clouds [9], and guide energy in the form of electric current and microwave radiations in air are now under development [10]. The latter is of great interest since it offers a solution to the natural divergence of the electromagnetic waves (EMWs) by confining the radiations and maintaining a high energy density over long distances equal to the filamentation length.…”

A hollow cylindrical plasma waveguide, which cladding consists of a large number of a chaotically distributed plasma filaments induced by the propagation of femtosecond (fs) laser pulses in air, is shown to support guided modes of pulsed infrared (IR) laser radiation. Taking into account the discontinuity and the finiteness of the waveguide cladding, the loss coefficient loss of the laser radiation is calculated for different spatial configurations. We report how the waveguide loss depends on its structural parameters like normalized plasma diameter, distance between filaments, core-radius, cladding's thickness, and filaments' electron density. For typical plasma parameters, the loss of the fs plasma waveguide is found to be lower than that of freely propagating IR laser beams to distances in the order of the filamentation length. This fact allows the delivery of collimated pulsed laser light over long distances in atmospheric air, which is necessary for optical-based remote sensing and the detection of chemical and biological agents.Plasma waveguide, Femtosecond laser pulse, the loss coefficient, Filamentation, Optical-based remote sensing.

Towards Laser Driven Hadron Cancer Radiotherapy: A Review of Progress

et al. 2014

It has been known for about sixty years that proton and heavy ion therapy is a very powerful radiation procedure for treating tumors. It has an innate ability to irradiate tumors with greater doses and spatial selectivity compared with electron and photon therapy and, hence, is a tissue sparing procedure. For more than twenty years, powerful lasers have generated high energy beams of protons and heavy ions and it has, therefore, frequently been speculated that lasers could be used as an alternative to radiofrequency (RF) accelerators to produce the particle beams necessary for cancer therapy. The present paper reviews the progress made towards laser driven hadron cancer therapy and what has still to be accomplished to realize its inherent enormous potential.
