The Pfl “squiggle:” an Independent Monitor of Trigger and Cascade Section Runtimes
The refurbished Z pulsed power driver has been operational since October of 2007 delivering a peak current of ~26 MA to the load. A critical component of the refurbished Z accelerator was the Laser Triggered Gas Switch (LTGS) with a maximum proven operating point of 6.5 MV, 820 kA and an overall 1-σ timing jitter of ~6 ns. We have identified a feature in the V-dot monitor on the Pulse Forming L...
متن کامل1.7MW Nd:YAG Laser Pulse Generation by A Passive BDN Q-switch
This paper describes the passive Qswitch, based on polymer and organic dye BDN, of a pulsed Nd:YAG laser. Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse charac...
متن کاملUnified Pulsed Laser Range Finder and Velocimeter using Ultra-Fast Time-To-Digital Converter
In this paper, we present a high accuracy laser range finder and velocimeter using ultra-fast time-to-digital converter (TDC). The system operation is based on the measuring the round-trip time of a narrow laser pulse. A low-dark current high-speed PIN photodiode is used to detect the triggered laser beam and to produce start signal. The pulsed laser diode generates 45W optical power at 30ns du...
متن کاملADVANCED PULSED POWER CONCEPT AND COMPONENT DEVELOPMENT FOR KrF LASER IFE*
The Electra advanced pulsed power development program has the goal of developing and demonstrating pulsed power technology that is applicable for KrF (krypton fluoride) Laser IFE (inertial fusion energy). The application presents efficiency, lifetime and cost challenges that mandate the use of advanced pulse compression topologies. In turn, these advanced topologies require the development of c...
متن کاملInfluence of shielding gas composition on weld profile in pulsed Nd:YAG laser welding of low carbon steel
Weld area and weld depth/width ratio can be considered to be of the most important geometrical factors in pulsed laser welding. The effects of carbon dioxide and oxygen additions to the argon shielding gas on the weld properties in pulsed laser welding of low carbon steel is investigated. Presence of carbon dioxide and oxygen up to 10 and 15 percent respectively decreases the weld geometrical f...
