Designed for high-speed micromaterials processing, Rofin-Baasel Lasertech’s PowerLine L laser series is targeted at photovoltaic manufacturing. The Q-switched solid-state lasers are designed for applications that require high average power and high pulse energy, such as thin-film removal on glass and flexible materials, ablation of dielectric layers, silicon processing, drilling and cutting. At 1064 nm, the PowerLine L 300 is used in edge deletion applications. It produces >200 W at 10 KHz and features an optimized square optical fiber with a 400-μm diameter. Compared with round fibers, square fibers provide higher efficiency by machining a bigger area per pulse. With selective opening of dielectric layers and direct laser doping, the device is suitable for use in mass production of enhanced solar cells. The frequency-doubled PowerLine L 100 SHG (second harmonic generation) is suitable for use in various research projects.
