High-Average-Power Lasers Platform
To accelerate the exploration of fundamental science across disciplines, including high-energy-density science, we developed “SENJU: Super Energetic Joint Unit” power laser available for experimental use. This laser delivers high pulse energy (up to 100 J) at a repetition rate (up to 100 Hz) that is five orders of magnitude higher than that of the conventional system (Gekko-XII). SENJU can be used cooperatively with the adjacent 40 TW-class femtosecond laser system.
