Six-beam high-power KrF excimer laser system with energy of 100 J/23 ns

In the ICF research, KrF laser is considered to be a promising candidate for the reactor driver due to its short wavelength, wide bandwidth, high efficiency, scalability, and advantages of UV laser in laser-plasma coupling. This paper describes some performance of 100J level multistage KrF laser system 'Heaven-I'. This high power KrF excimer laser system is under development in China Institute of Atomic Energy.
