Presented at ICALEO 2012
A pulsed fiber laser has been widely used for the removal of TCO film, since it is the compact oscillator with the flexible processing head. However, the wide range of emission wavelength from the fiber laser would deteriorate the edge quality of groove such as cracks and burr...$28.00

Presented at ICALEO 2012
High average power, high repetition rate ultrashort pulse ( < 10 ps) laser systems with μJ pulse energies [1, 2] are increasingly used for bio-medical and material processing applications. Interesting applications for the ultrashort pulse laser systems are in the field of selective structuring of thin-films. Thin-film solar cells hav...$28.00

Sub microstructures on metal surfaces find a manifold of applications ranging from anti-icing to terahertz detectors. So far demonstrations have been realized with femtosecond Ti:Sa laser only. To obtain a high throughput and industrially relevant texturation process a comparison of femtosecond processing is given between low repetition...$28.00
