For a mid-gap laser-triggered spark gap, three different physical mechanisms can be used: nonresonant multiphoton ionization, resonant-enhanced multiphoton ionization and electron tunneling. The first one is tradition all y used, wher eas the latter two are more exploratory. In this work, the traditional method is employed to study the delay time and time jitter of a laser-triggered spark gap using a Nd:YAG laser at 1064 nm and 532 nm, where the laser pulse is guided via an optical fibre to the spark gap; the laser pulse energy and the applied voltage have been varied for different working gases. One draw-back of the current laser triggering technology compared to other triggering techniques is that laser systems are more complex and prone to electromagnetic interference. Another downside is that the pulse-repetition rate is poor. A discussion about the development of lasers to overcome these issues is included, together with a deliberation about the pros and cons of the two exploratory methods of laser triggering. © 2013 IEEE.||Source Title:||Digest of Technical Papers-IEEE International Pulsed Power Conference||URI:||http://scholarbank.nus.edu.sg/handle/10635/116094||ISBN:||9781467351676||DOI:||10.1109/PPC.2013.6627479|
