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.

Fig. 2: Schematic of a pulse sequence

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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
