Abstract

By means of nonresonant multiphoton ionization using a picosecond pulsed YAG laser, pressure measurement for H₂, CO and CO₂ gases was carried out in the XHV pressure range. It was experimentally verified that pressure measurement was possible in the range of 10-11 Pa, and this pressure measurement method had pressure sensitivity of the same order of magnitude for the three molecules.
