Analysis of LED arrangement in an array with respect to lens geometry

Ley, Peer-Phillip; Held, Marcel Philipp; Lachmayer, Roland (Bellingham, Wash. : SPIE, 2018)

Highly adaptive light sources such as LED arrays have been surpassing conventional light sources (halogen, xenon) for automotive applications. Individual LED arrangements within the array, high durability and low energy ...
Efficient magneto-optical trapping of a metastable helium gas

Pereira Dos Santos, F.; Perales, F.; Léonard, J.; Sinatra, A.; Wang, J.; Pavone, F.S.; Rasel, E.; Unnikrishnan, C.S.; Leduc, M. (Les Ulis : EDP Sciences, 2001)

This article presents a new experiment aiming at BEC of metastable helium atoms. It describes the design of a high flux discharge source of atoms and a robust laser system using a DBR diode coupled with a high power Yb ...
Improving weld bead homogeneity in short arc GMAW processes applying low power diode lasers

Leschke, Jan; Zokoll, Erik; Hermsdorf, Jörg; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2018)

Using laser and arc power in equal parts, laser-arc hybrid welding processes are successfully adapted by the industry. This paper shows the stabilizing effects of diode lasers on short arc GMAW (gas metal arc welding) which ...
Optical coupling of bare optoelectronic components and flexographically printed polymer waveguides in planar optronic systems

Wang, Yixiao; Wolfer, Tim; Lange, Alex; Overmeyer, Ludger (Bellingham, Wash. : SPIE, 2016)

Large scale, planar optronic systems allowing spatially distributed functionalities can be well used in diverse sensor networks, such as for monitoring the environment by measuring various physical quantities in medicine ...
Rapid prototyping of reflectors for vehicle lighting using laser activated remote phosphor

Lachmayer, Roland; Kloppenburg, Gerolf; Wolf, Alexander (Bellingham, Wash. : SPIE, 2015)

Bright white light sources are of significant importance for automotive front lighting systems. Todays upper class vehicles mainly use HID or LED as light source. As a further step in this development laser diode based ...
Temperature issues with white laser diodes, calculation and approach for new packages

Lachmayer, Roland; Kloppenburg, Gerolf; Stephan, Serge (Bellingham, Wash. : SPIE, 2015)

Bright white light sources are of significant importance for automotive front lighting systems. Today's upper class systems mainly use HID or LED light sources. As a further step laser diode based systems offer a high ...
