Feasibility of constructing a 100 TW femtosecond 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 duration shorter than the reciprocal of the gain bandwidth, a steep leading edge, and a high contrast. A basic four-channel system with consecutive addition of pulses involving stimulated Raman scattering is proposed. It is shown that the total output power can reach 120 TW.
