Absorption Backscattering and Mirror Reflection from Laser and Microwave Plasmas

Abstract

Research on an improved 8-10 GHz microwave system for propagation, reflection and absorption studies of VUV excimer laser (193 mm) produced plasmas has been carrier out. We have obtained high density ne =2-5x10 13/cm3 laser formed plasmas which are 9cm wide x 40cm long x 3-20 mm thick and demonstrated that diffusion is small for time scales less than a microsceond. Preliminary results show that the initial high density plasma obtained in TMAE at 30-60 m Torr pressures has a reflection coefficient comparable to aluminum.
