“…This behavior indicates an increasing gain in the laser up to a pressure of 4.5 bar, due to an increased efficiency in the formation of the ArF molecule due to three-body collisions [20], [24]- [27], [29], [30] and an increased efficiency in the power deposition [31]. The intensity decrease at higher pressures is probably caused by a worse discharge quality due to the higher pressure and an increased quenching of the ArF molecules by Ne [20], [24]- [27].…”

An X-ray preionised, discharge excited ArF excimer laser, = 193 nm, has been studied in the long pulse regime. The laser performance is found to be primarily dependent on the discharge stability, and therefore, on the gas composition, preionization timing and the pumping power. Using X-ray preionization and prepulse-mainpulse excitation, laser pulselengths of up to 120-ns full-width at half-maximum at 4 mJ/`are obtained by decreasing the partial pressures of the active ingredients, F 2 and Ar, and using Ne as a buffergas. This is almost six times as long as usual for discharge excited ArF lasers.

“…This technique would yield a wide range of attainable temperatures and flow conditions. As compared with arc or laser powered discharge heating [1,2], non-resonant pulsed optical lattices offer the possibility to study high temperature gases without the ionization and molecular dissociation reactions associated with discharges. Traditional shock tubes, often used for high temperature flow studies [3,4], are characterized by very short interaction/probe times and significant deviations from thermal equilibrium.…”

“…External electromagnetic fields are thus often used for accelerating them, narrowing their thermal velocity distribution, also for deflecting, focussing, or keeping parallel the beam in order to transport and utilize it effectively. Charged particle beams were first used for atomic and nuclear physics, and are now also applied to plasma diagnostics, space propulsion applications, film deposition [21] and ion implantation for microelectronics, to perform precision electron beam welding, rapid cutting of thermosetting plastics, cross-linking of thermoplastics to improve their physical properties, promote or increase plasma chemical activity, to invert the population of a gas laser and give rise to light amplification (from the soft X-ray region to the far infrared) [13], to control thermonuclear reactions via plasma heating [5], to process of surface treatment and depollution of high-volume exhaust streams [13], to support externally nonself-sustained discharges, or to study stellar plasma. Some of these listed applications combine an electron beam interacting with a plasma.…”
