Presented at ICALEO 2009
The InnoSlab laser design, already established for neodymium doped laser materials, was applied to ytterbium doped laser materials. Nearly transform limited sub-picosecond pulses at 400 W average power at room temperature and without using CPA technique have been achieved so far. This compact, diode-pumped Yb:YAG InnoSlab fs-osc...$28.00

Presented at ICALEO 2009
CO2 lasers can be seen to lend themselves to materials processing applications. These types of lasers have been used extensively in research and industry with the work carried out being well documented. This work investigated the surface modification of PMMA with a CO2 laser in order to vary wettability characteristics. The wettability characteristics of the PMMA were modified by generating a number of patterns of various...$28.00

Presented at ICALEO 2009
The properties of ZnO single crystal irradiated by a pulsed 248nm excimer laser have been systematically studied by AFM, XRD, photoluminescence and Raman measurements. It was observed that the surface roughness and the grain size on the surface of the irradiated ZnO crystals became larger, as well as their band-edge (BE) emissions at room temperature were found to become stronger and s...$28.00

Presented at ICALEO 2009
This paper aims to contribute to the understanding of laser irradiation effect on the electric and photoluminescence (PL) properties, surface morphology of ZnO thin films. By optimizing the laser beam quality and optical system, with changing the laser parameters, the carrier concentration and UV PL intensity of ZnO thin films could be increased and modulated in a wide range. At a moder...$28.00

Presented at ICALEO 2009
We report the use of short pulse laser ablation as a technique for mitigation of near surface stress and damage in SiC. Conventional machining, grinding or polishing of SiC renders a damaged surface layer of depth approximately equal to the final peak-to-valley roughness. This damage layer is comprised of compressive stress and represents a threat to the integrity of the mate...$28.00
