Designed for speed in the PV material world
ROFIN has introduced the PowerLine L Series, a new laser series for high-speed micro material processing with a special focus on photovoltaic manufacturing.
With its new PowerLine L series, ROFIN has introduced q-switched solid state lasers specifically designed for micro material processing applications which require high average power and high pulse energy. Examples are thin film removal on glass and flexible materials, ablation of dielectric layers, silicon processing, drilling and cutting.
In the 1064 nm class, the PowerLine L 300 completes ROFIN‘s laser range for edge deletion applications. Whereas ROFIN‘s DQ series offers 500 to 1000 watts, the PowerLine L 300 features more than 200 W laser power at 10 KHz and smaller optical fibres, especially an optimized square fibre with 400 µm diameter. Compared to round fibres, square fibres provide the highest efficiency by machining a bigger area per pulse.
Selective opening of dielectric layers and direct laser doping currently draw a lot of interest in crystalline solar cell manufacturing. For both applications the frequency- doubled PowerLine L 100 SHG already proved its perfect
applicability in various research projects ongoing.
The laser source offers optimum beam characteristics and sufficient power for large production scale. Green lasers with 532 nm show the desired near-surface absorption in silicon and can be equipped a wide range of long-living optical components and fibres. With optimized fibres, a top-hat beam profile can be realized which provides homogenous energy distribution within the entire laser spot area.
The Nd:YAG lasers are efficiently diode pumped and designed for industrially reliable 24/7 operation. The PowerLine L 100 SHG uses a high performance SHG assembly with harmonic generator crystal for frequency conversion. The unique principle of q-switching make peak pulse performances possible that are a 1000 times higher than the cw laser power. Standard configuration includes a fibre delivery to the processing head. Optionally accessories as fibre outcoupling and scan head assemblies supporting scan speeds of > 10 m/sec at unmatched precision are being offered.
