The Project ABCD, a diode pumped glass laser for Research on inertial fusion energy at the Associazione Euratom-ENEA sulla Fusione in Frascati

The Laboratory for ICF Physics and Technology of the CR ENEA in Frascati is currently performed activity for the development for potential drivers for Inertial Fusion Energy. The system being considered for a possible future development is a diode-pumped neodymium glass laser (HAP-4) dimensioned to deliver 100/spl divide/400 J in pulses of 1/spl divide/5 ns at a rate of 1/spl divide/10 Hz. The name of this system is ABCD, after ABC, the name the two beam, flash lamp pumped laser currently used for experiments on Inertial Fusion Energy (IFE) in Frascati. The main ABCD amplifier architecture is based on a 5-pass cavity that includes a system of 7 sub-amplifiers formed by assembling two modules.
