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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
