Micromachining Technology
ZURICH, Switzerland, Aug. 17, 2009 – Time-Bandwidth Products AG has introduced the FlexBurst technology for its 10-W Duetto and 50-W Fuego picosecond lasers, enabling new processing possibilities in micromachining.

Time-Bandwidth-FlexBurst.jpg“Burst” refers to a group of 10-ps pulses with a temporal spacing on the order of tens of nanoseconds. Recent demonstrations have shown that such bursts have the potential to improve materials processing speed as well as quality. The leading pulses pre-condition the material in such a way that trailing pulses hit it in a different state, which increases process performance.

In current picosecond micromachining lasers that offer multimegahertz bursts, the pulse energy distribution within the burst cannot be controlled by the user. The pulse energy decreases due to gain depletion in the amplifier, and such a distribution is not ideal for materials processing applications.

The FlexBurst technique allows for the generation of bursts with full user control of the pulse energy distribution to better match process requirements. Because the energy of each pulse can be arbitrarily set, it is possible to equalize pulse energies, to achieve controlled increasing or decreasing pulse energies and to blank intraburst pulses with virtually no restrictions.

The repetition rate of the bursts can be set in the range from 50 kHz to multimegahertz, with burst energies of greater than 200 µJ.

GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
