High current transistor pulse generator [PDF]

open access: yesConference Record of the 1991 IEEE Nuclear Science Symposium and Medical Imaging Conference, 2002
A solid-state pulse generator capable of delivering high-current trapezoidally shaped pulses into an inductive load has been developed at SLAC (Stanford Linear Accelerator Center). Energy stored in the capacitor bank of the pulse generator is switched to the load through a pair of Darlington transistors.

A continuous discharge improves the performance of the Cu/CuCl double pulse laser [PDF]

open access: yes, 1979
A continuous glow discharge was applied to a Cu/CuCl double pulse laser. Maximum laser pulse energy was observed to increase as much as 35 percent at low buffer gas pressure and 3.5 percent at optimum buffer gas pressure.
