LIA’s Northeast Chapter Meeting – Well Attended

A meeting of the Northeast Chapter of the LIA was held on April 20, 2011 in New Hampshire.  This meeting featured a plant tour of PhotoMachining, Inc. – a high resolution laser job shop and systems integrator.  Many different laser workstations and demos were presented, but in particular – holding with the theme of the event – the in house Lumera Super Rapid laser was shown.  This laser is set up for using three different wavelengths (1064nm, 532 nm and 355 nm) at a 12 ps pulse length and delivered through a galvanometer beam delivery system with accompanying table motion.  About 40 people attended the tour and then adjourned to the event hotel – the Crowne Plaza in Nashua, NH.

ILSC 2011 – A Closer Look at Laser Safety

Presented by LIA, the International Laser Safety Conference (ILSC®) is a comprehensive four-day conference covering all aspects of laser safety practice and hazard control. Laser safety experts from around the world descended on San Jose, Calif. to discuss and define the latest changes to regulations and common practices in the field. Held March 14-17, 2011, scientific sessions addressed developments in regulatory, mandatory and voluntary safety standards for laser products and for laser use. Continue reading

Newport Introduces New Laser µFAB™ – Microfabrication Workstation

Newport Corporation, a worldwide leader in lasers and photonics solutions that Make, Manage and Measure Light®, introduces the Laser µFAB, a tabletop laser microfabrication workstation optimized for research applications.  The Laser µFAB is designed for use in both additive and subtractive processes, including 3D microfabrication by two-photon polymerization (TPP), laser ablation and surface structuring of various materials, volumetric writing of waveguides and microfluidics, nanosurgery, microdissection, and others. Specific research applications using TPP in custom or commercial photoresists, include photonics, microelectronics, and MEMS.  Relevant industrial materials that can be used in ablation and surface structuring applications include metals, polymers, semiconductors, glasses, ceramics,  and biological targets.  Waveguides and microfluidics can be volumetrically written in glasses and polymers.  Nanosurgery and microdissection can be done in vivo for sub-cellular investigations of model organisms.

Fraunhofer Institute for Material and Beam Technology (IWS)

Laser additive manufacturing with diode, fibre or disc lasers offers outstanding possibilities for applications in aircraft manufacturing or maintenance. High-precision laser additive manufacturing requires precise tolerances of all the components like laser beam, machine configuration, powder delivery, media supply as well as process parameters and control. Only the right interaction of all components leads to precise structures. Fraunhofer IWS in Dresden has a wide experience in improvement of processes and system components for laser additive manufacturing of aircraft components and excellent equipment. Continue reading
