Abstract

The European laser driven fusion project HiPER relies on kilojoule, nanosecond pulse trains with repetition rates close to 10 hertz and high wall-plug efficiency. We propose a scheme based on diode-pumped amplifiers using Yb3+:YAG ceramics as gain medium. An active mirror architecture where the high reflection coated side is cooled using a low pressure static Helium gas cell, is proposed.
