DiPOLE100: A 100 J, 10 Hz cryogenically cooled Yb:YAG diode pumped solid-state laser

The requirement for high energy, high repetition rate DPPSL systems is rapidly growing with a range of demanding applications waiting including, pump sources for high-intensity PW-class amplifiers; direct sources for studying new material processing techniques or exploring high energy density physics phenomena. To meet this challenge the DiPOLE project at the Central Laser Facility (CLF) is developing an efficient high pulse energy DPSSL architecture based on a cryogenic gas cooled, multi-slab ceramic Yb:YAG amplifier concept, capable of amplifying ns pulses to kJ pulse energies [1, 2].
