Two new laser micromachining processes developed for the production of channels and voxels with highly repeatable micrometer level resolution will be presented.

Devices fabricated with this developed technology can be used for applications such as microfluidic lab on a chip, strain measurement, sub-micrometer cooling systems and various photonic guiding systems.

These systems include automated 3D Nd:YVO4 and CO2 lasers for microprocessing. In order to achieve the precise control, CAD processing, laser firing, 3D sample movement and thermal field modelling software were developed. Additionally, for the characterisation and optimisation of these processes an automated channel and voxel profiler was developed and built in-house. Details of the system and the high efficiency achieved from these processes, will be presented.

AILU one-day technology workshop as part of the Industry and Technology Programme at Photon08.

Photonics is an enabling technology for many products in different sectors. Increasingly important in all areas this seminar is designed to highlight developments in laser technology as applied to medical and biophotonics areas. The burgeoning specialism of photonics in the medical sector is addressed in this one-day meeting as part of Photon 08.

Duncan Hand of Heriot-Watt University will be chairing the event.

This is a Medical Group event - for more information about the Medical Special Interest Group or to join contact the  AILU Office.
