Laser propagation in a highly magnetized over-dense plasma

TL;DR

This paper analytically investigates how right-hand circularly polarized lasers propagate through highly magnetized, over-dense plasmas, demonstrating efficient plasma heating from 100 eV to 1 keV within a short depth and time frame.

Contribution

It provides an analytical study of laser propagation in highly magnetized, over-dense plasmas, revealing efficient heating mechanisms under specific conditions.

Findings

Plasma density of 10^23 cm^-3 can be efficiently heated from 100 eV to 1 keV.

Laser irradiance of around 10^14 W/cm^2 is effective for rapid plasma heating.

Heating occurs within approximately 20 micrometers depth in about one nanosecond.

Abstract

Propagation of right-hand circularly polarized laser into highly magnetized over-dense collisional plasma is analytically studied from basic equations. Highly magnetized plasma with density of 10^23 cm^-3 is efficiently heated from 100 eV to 1 keV within depth of around 20 \mu{m} in one nanosecond by Nd:YAG laser with moderate irradiance of around 10^14 Wcm^-2.
