Plasma Production by CO2 Laser

  • Klaus P. Büchl

Abstract

Plasma production from solid hydrogen targets with laser radiation at 0.69 μ and 1.06 μ has been well investigated in past years and good agreement has been found between a model based on hydrodynamic calculations and experiments. The model was developed by Afanasyev, Krokhin and Sklizkov1, Caruso and Gratton2, Mulser3 and others. It assumes that the absorption of laser radiation is due to inverse bremsstrahlung at the surface of the solid target. A hot plasma is produced and expands towards the laser into the vacuum. Then the radiation will be absorbed in the plasma near the critical density ne, which is given by
$${n_c} = \frac{{\omega _L^2\,\,{m_e}}}{{4\;\pi \;{e^2}}}$$

where ωL is the laser frequency.
