XeF-laser with longitudinal discharge excitation

A KrF-laser excited by a capacitively coupled longitudinal discharge

“…spectroscopy and testing purposes. Though transverse discharge systems can be scaled down to a small size [1], other excitation schemes as longitudinal [2,3] or capacitively coupled longitudinal [4] and transverse [5] discharges may be appropriate for excimer lasers with output energies ranging from several 10 ~J to some mJ. These alternative excitation techniques offer a similar power deposition capability compared to that of conventional transverse discharge devices.…”

Longitudinal KrF lasers with improved efficiency and operating period

“…Table 1 summarises the different discharge circuits which were employed. Circuits A-C represent our conventional [3,6] longitudinal discharge arrangement with internal anode and cathode and an additional capacitive electrode, whereas circuits D-E are pure capacitively coupled discharge arrangements [3, 51.…”
