We are preparing for a POP (proof-of-principle) demonstration of 400 MeV H- stripping to proton by using only lasers at J-PARC RCS. We will utilize both IR and UV lasers in a three step process of stripping an H- to proton. The laser system especially a prototype of the IR laser, which is a YAG laser is under development through experimental studies of 3 MeV H- neutralization at J-PARC. We have also developed a multi-pass laser cavity system to significantly reduce the seed laser power. We have also started developing the a UV laser and we plan to carry out first stage of the POP demonstration in 2022.
