In this paper, the first study of jitter in a laser triggered spark gap switched by pulse trains from a mode-locked ruby laser is described, where the gap was fired by producing gas breakdown in a high pressure argonnitrogen mixture between the pole pieces.Abstract:
The first study of jitter in a laser triggered spark gap switched by pulse trains from a mode‐locked ruby laser is described. The spark gap was fired by producing gas breakdown in a high pressure argon‐nitrogen mixture between the pole pieces. Jitter was measured as a function of the position of the lens used to focus the laser beam and as a function of the ratio of the applied voltage to the self‐breakdown voltage of the gap. Jitter values of less than 2 nsec were obtained under optimum conditions provided that the gap was fired by the early part of the pulse train.read more
