Abstract

To obtain the proper conditions for inversion and gain in 'pure' photopumped x-ray laser systems it is normally considered necessary to separate the pump and lasant. This is due to the fact that a plasma which produces adequate pump power is usually too hot and/or dense to sustain lasing. Thus there is a need for separate plasmas at significantly different conditions. In this paper we explore the question of whether the recent rapid development of ultraintense, short-pulse lasers can change this picture by altering the relationship of electron temperature to degree of ionization.
