Author Affiliations +
The Diode Pumped Optical Laser Experiments (DiPOLE) project at Central Laser Facility (CLF) is aimed at the development of scalable diode pumped, cryogenic gas cooled, multi-slab Yb:YAG amplifiers. Optimized designs for amplifiers capable of generating kJ pulse energies at multi-Hz repetition rate have been finalised and development of a scaled-down 10J, 10Hz prototype is currently underway at the CLF. We report on the recent results obtained on a 4-pass bowtie as well as 6-pass image relaying multi-pass setup for the DiPOLE amplifier. Additionally, Preliminary results for the amplifier performance with uniform doping (3 × 2at%) compared to gradient doping (2 × 1at% + 2 × 2at%) at cryogenic temperatures, confirms the multi-slab gradient doped design adopted for DiPOLE amplifier.
