Micro-Nano SIG

 


The Micro:Nano SIG was launched at AILU's 10th microprocessing workshop in June 2008. Lasers are a key technology in the micro and nano-engineering fields, where they provide high-resolution, accuracy, speed and flexibility. The engineering of micro features is key to the technical and commercial success of many mass-produced components ranging from photovoltaic cells, inkjet print heads and flat panel displays, to MEMS components and disposable medical instruments. It is to address the special needs of this burgeoning sector that AILU launched the Micro:Nano group.

The activities of the Micro:Nano Group will address the interests of laser processing

Message from the Chair by Jack Gabzdyl

July 2013

Interest in laser micro processing is certainly on the up. For example, 6 of the 16 technical sessions of the most recent Industrial Laser Applications Symposium (ILAS 2013) were devoted to micro-machining! These presentations covered applications for a broad range of lasers, wavelengths and pulse durations, and the processing of an equally diverse range of materials. The overall message was certainly that lasers are good at making small features! So whether you are looking to manufacture fibre optic cantilever sensors or want to texture a surface to control cell behaviour, lasers are the tool of choice and more importantly these lasers are invariably pulsed.

The use of Ultra Short Pulse lasers is certainly gaining momentum and the use of short pulse durations (<1ns), with high peak powers and small processing spot sizes generates the extreme energy intensity that generates high quality machining that many end users are looking for. What is perhaps intriguing about operating in the USP regime is that exact laser wavelength becomes of less importance to the processing.

The number of suppliers offering industrial sources is also increasing and at the recent Munich World of Photonics exhibition in May, USP lasers had high visibility. What is still the case is that short pulses still command a significant premium, with USP lasers costing an order of magnitude more in terms of £/W than some ns-pulse fibre laser sources.

The UK has a strong background in micro-machining, both on an academic and laser source/system integration level. There is also a thriving related exhibition - MM, MEMs & Nano Live UK - which this year takes place on 25-26 September at the NEC Birmingham. The event has been growing year on year, bucking the trend of many other exhibitions where visitor numbers have been in decline. AILU’s Micro & Nano Special Interest Group helps network the UK’s interests in micro laser processing. Its annual workshop provides an excellent forum for promoting and sharing the latest innovations in laser sources, systems and applications with a combination of inputs from academia, suppliers system builders and end users.
Members who would like to be involved should contact me or the AILU office.

Accessing the on-line Micro:Nano SIG Forum

To access the forum you first need to login using your assigned name and password. If you selected 'remember my password' when you last logged in you will already have access to the forums, otherwise the entry point is in the top right corner of this page. (tip: If you are still using the random number/letter password you were originally given, why not change it to something memorable by clicking on the ‘edit details’ link after you’ve logged in?)

Once you do this a link to the forum will appear in the left hand links column under ‘Laser User Groups’.
