Disk Lasers in the Photovoltaic Industry

Diverse types of lasers, such as nanosecond, pulsed, and excimer, have been considered for various applications in the photovoltaic industry, including edge isolation, edge deletion, drilling for back contact, cutting of Si-wafer, and patterning of crystalline solar cells. High power lasers, with high stability and high efficiency in addition to high beam quality, are needed now more than ever.
