OPTICAL BREAKDOWN THRESHOLDS OF RARE GASES XE AND KR IN A WIDE FREQUENCY RANGE

An experimental determination was made of the optical breakdown thresholds of rare gases Xe and Kr in a wide (including ultraviolet) range of wavelengths and radiation intensities. Measurements were made at pressures of 200 and 760 Torr using the first to the fourth harmonics of single-mode frequency-stabilized neodymium laser radiation.
