FEASIBILITY OF CONSTRUCTING A 100 TW FEMT OSECOND ELECTRIC-DISCHARGE EXCIMER SYSTEM

Numerical simulation is used to show that conversion of radiation from a femtosecond XeCl excimer system by stimulated Raman scattering can be used to generate pulses with unique characteristics: a shorter dura tion, a smaller reciprocal of the width of the gain band, a steep lead ing edge, and a high contrast. A basic four-channel system with consec utive addition of pulses involving stimulated Raman scattering is prop osed. It is shown that the total output power can reach 120 TW when 21 beams of 1 J energy each are amplified in an electric-discharge outpu t module with an interelectrode distance of the order of 10 cm.
