Reabsorption and amplification of radiation in non-equilibrium plasma

Abstract

Variation of radiation intensity in plasma with non-equilibrium particle distribution is usually described by the radiation transfer equation (4.3). Intensity of radiation escaping a homogeneous layer of geometrical thickness L is equal to

$$ {I_{w\, = \,\frac{{a{\,_w}}}{{{\mu _j}}}}}\,\left( {1\, - \,e{\,^{ - \,\mu {\,_{j{\,^L}}}}}} \right)\, + \,I{\,_{w{0^{e{\,^{ - \,\mu \,j\,L\,}}}}}} $$
