Presented at ICALEO 2011
New dimensions in precision and the variety of machinable materials are enabled by the use of ultrashort laser pulses in material processing. Due to new powerful beam sources the processing efficiency has already reached an economic interesting state. Based on a regenerative disc amplifier the Dausinger + Giesen GmbH has developed a femtosecond source that is distinguished on its high flexibility and high pulse energy. Out of one res...$28.00

Presented at ICALEO 2011
Laser microprocessing is key to the development and manufacture of advanced silicon photovoltaics. In this paper a picosecond laser is used to pattern and mark the surface of both textured and non-textured passivated silicon photovoltaics as well as unpassivated silicon wafers. The laser is a master oscillator fiber power amplifier that provides 30 picosecond pulses at 532 nm with pulse energy up to 5 micro-Joules. We evaluate and compare techniques...$28.00
