Presented at ICALEO 2010

A study on the nanosecond fiber laser interaction with silicon was performed experimentally for the generation of percussion drilled holes. Single pulse ablation experiments were carried out on single crystalline 650µm thick silicon wafers. Changes of the mass removal mechanism were investigated by varying laser fluence up to 45 J/cm2 ...

As the average power for short pulsed lasers (femto-, pico- and nano- second pulse durations) increases, it may be economical to transition from micro to macro laser machining applications. Removal rates have usually been driven by parameters that meet a given surface finish and/or dimension requirement that can be achieved with a gi...

Presented at ICALEO 2010

Nanosecond pulsed fiber lasers have made a significant impact in the material marking arena, but as laser sources they are proving to be extremely versatile finding many applications in a variety of micro-machining processes. One such process is micro-cutting.

Until recently high precision micro cutting has been the domain of DPSS pulsed lasers and CW-M fiber lasers, as epitomised by applications such as electronic stencil and medical stent cutting. However the short high peak power pul...

Presented at ICALEO 2010

Micro structuring of sapphire and fused silica is an important market e.g. for microfluidic devices and sensors that combine optical and microfluidic features, freeform microlense systems as well as micromechanical parts. New techniques which enable more material and time efficient processing of sapphire and fused silica are requested.
The In-volume Selective Laser Etch...
