ABSTRACT:
A high intensity light source having high repetition rate and narrow pulse-width. The light source comprises a metal casing having coaxially mounted arcing electrodes therein which utilize the capacitance of the coaxial system to charge up to the arcing potential. One electrode is electrically connected to the end wall of the casing to provide a reflected wavefront from the end wall after an arc has been struck, such wavefront serving to extinguish the arc and thus provide a sharp pulse. The lamp may be used for such areas as photochemical and photobiological research, in place of much costlier nanosecond lasers.
