Sterilization Performance of Ultraviolet Emission from Laser Plasmas
A pulsed YAG laser beam was focused with a lens in order to produce laser plasmas by laser-induced gas breakdown inside the gas cell. The most intense UV emissions between 200 and 300 nm in wavelength was generated by the Xe gas breakdown. UV emission from laser plasma by Xe gas breakdown showed the best sterilization performance compared with those by other gas breakdown.
