FlexPulse: Picosecond pulses with arbitrary pulse sequence and energy

15.06.2015

The company neoLASE provides short pulse laser systems by combining innovative pulsed laser sources with well-established and reliable solid state lasers. A new developed, compact laser system will now enable picosecond laser pulses with a unique flexibility in terms of pulse sequence control.

The increasing demands in laser material applications require high flexible and comprehensive laser systems.

For these areas neoLASE developed a new picosecond laser system with a unique flexibility in terms of pulse control.

With the flex pulse technology the lasers repetition rate and the pulse energy can be changed continuously. The system is based on a laser diode emitting 70 ps long laser pulses which can be triggered (PLS) for each pulse individually.

The pulses sequence therefore can be arbitrary and set from single pulses up to 80 MHz repetition rates or can be synchronized with scanners or moving axes.

The use of a frequency sweep for example can produce gray scale pictures without changing the scanners speed (Fig.1). A second control input (PWR) enables free pulse energy control up to 250 µJ which can be correlated to changes in the repetition rate or adapted to different processing steps.

The full flexibility of the system is illustrated in Fig.2 showing that the pulse sequence and energy can be adapted to the application.

This and other new developments will be presented at neoLASE booth on Laser World of Photonics Hall A3 booth 438/2 or visit neoLASE webpage under www.neoLASE.com

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
