To improve the beam quality and output powers of driving optical components for Inertial Confinement Fusion (ICF) laser facilities
this paper introduces the construction
operation and performance enhancement of SG series laser facilities in China. It reviews the research working and developments of optical components for the ICF laser facilities in recent years. These workings involve the preparation of raw materials
such as high purity metal hafnium (Hf) and Potassium Dihydrogen Phosphate (KDP)
and the melting
processing and growing of four kinds main materials
including neodymium glass
high purity KDP
fused quartz and KDP/DKDP (doped deuterium KDP). For fabrication of the optical components
it describes the cold machining technology for neodymium glass
white glass
KDP crystals and the coating technology for dielectric films and chemical films. Finally
the paper also focuses on some key test technologies of the large diameter optical components in process inspection and final inspection. These key technologies and machining processing proposed in this paper meet the most requirements of the optical components in whole machining process and improve the development and production capacities of optical components in ICF laser facilities.
