ScholarBank@NUS Repository. https://doi.org/10.1109/PPC.2013.6627479 | Abstract: | Switching time jitter is one of the important properties to consider when selecting a closing switch for a pulsedpower system, and the most time-precise triggering can be achieved by the use of lasers. 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 |
