Abstract : A study of gas breakdown induced by the ultraviolet second harmonic of ruby laser radiation has revealed an anomalously high threshold intensity for hydrogen. In addition, it has been demonstrated for the first time that the focal volume dependence of the breakdown threshold, of a number of molecular and noble gases, is influenced by the frequency of the incident radiation.
