Industrial Laser Solutions;May/Jun2010, Vol. 25 Issue 3, p15
The article reports the alternative energy sources due to global warming and foreign energy dependence including the thin-film photovoltaic (TFPV) manufacturing. He discusses the lasers for thin-filming scribing with Q-switched diode-pumped solid-state (DPSS) lasers and the better beam quality or M2 factor to lower manufacturing costs and increase high quality scribe process. He concludes that through correct laser system can contribute in obtaining a high-yield robust process.
