Optical Inspection of Material Surface Quality Changes with Laser Displacement Sensors, Including Applications to Laser Inertial Fusion

抄録

A new method to estimate erosion threshold of various material surfaces with a high-power pulsed electron beam [Appendix] was extended to the surface erosions with various pulsed laser lights. The most interesting result was that the CVD polycrystalline diamond had similar erosion threshold as tungsten. After our extended experiments of this kind in the near future, novel plasma-facing surface materials are expected to be realized for future fusion reactor chambers.
