HiLASE: Development of Fully Diode-Pumped, kW-Class Pulsed Lasers for High-Tech Applications

摘要

The main goal of HiLASE project (High average power pulsed LASErs) is to create a solid platform for development of advanced DPSSLs in the Czech Republic. Two key concepts are being explored within HiLASE: thin-disk laser amplifiers to reach kW average output power, and cryogenically cooled multislab laser amplifiers to reach 100 J at 10 Hz output, scalable to kJ regime. There are three separate thindisk beamlines under construction with different output parameters: Beamline A (750 mJ, 1.75 kHz, 3 ps), Beamline B (500 mJ, 1 kHz, 2 ps), and Beamline C (5 mJ, 100 kHz, I ps). In addition, a singlebeam 100 J class nanosecond laser system based on a gas-cooled cryogenic, diode-pumped Yb:YAG multi-slab architecture with wall-plug efficiency > 12% and repetition rates up to 10 Hz is now under construction and will be commissioned by August 2015. DPSSL systems deployed in the HiLASE facility shall be at a disposal of external users for testing and prototyping of various laser technologies, and for contract research and development.
