Abstract This work reports on the application of a novel electric field-ionization setup for high-resolution laser spectroscopy measurements on bunched fast atomic beams in a collinear geometry. In combination with multi-step resonant excitation to Rydberg states using pulsed lasers, the field ionization...
Full size table Our solver calculates all these parameters and automatically activates new super-layers of the deforming mesh according to time spans of preheat and dwell stages. It also automatically changes the boundary conditions when it is time to cut the completely printed and cooled-down part...

The pulse energy needed for low numbers of pulses is double that for high numbers while the repetition rate stays within 20% of the maximum. To reduce machining time, high repetition rates are desired along with low numbers of pulses, however the repetition rate is already at its maximum for...

The concept of electron acceleration by a laser beam in vacuum is attractive due to its seeming simplicity, but its implementation has been elusive, as it requires efficient electron injection into the beam and a mechanism for counteracting transverse ex
(Polycut E, Reichert-Jung, Germany) to provide a plane surface for compression tests. For the laser ablation extraction, a spiral inbound anticlockwise hatch pattern was centred around each fibre, from an outside diameter of 300μμminward to 150μμm(Fig.1b). Each successive radial pass ...
