Rofin-Baasel LasertechRequest Info
Designed for high-speed micromaterials processing, Rofin-Baasel Laser-tech’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. In the 1064-nm class, the PowerLine L 300 completes the company’s laser range for edge deletion applications. It produces >200 W of laser power at 10 KHz and features an optimized square optical fiber with a 400-μm diameter. 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. The laser source offers optimum beam characteristics and sufficient power for large production scale. The 532-nm green laser produces near-surface absorption in silicon and can be equipped with a wide range of long-living optical components and fibers.

1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
The process of forming a lens to a given pattern, or of cutting a piece of glass along the line of scratch.
A noncrystalline, inorganic mixture of various metallic oxides fused by heating with glassifiers such as silica, or boric or phosphoric oxides. Common window or bottle glass is a mixture of soda, lime and sand, melted and cast, rolled or blown to shape. Most glasses are transparent in the visible spectrum and up to about 2.5 µm in the infrared, but some are opaque such as natural obsidian; these are, nevertheless, useful as mirror blanks. Traces of some elements such as cobalt, copper and...
optical fiber
A thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower index material to promote total internal reflection (TIR). It may be used singly to transmit pulsed optical signals (communications fiber) or in bundles to transmit light or images.  
second-harmonic generation
A process whereby two fields of the same optical frequency interact in a nonlinear material to produce a third field, which has a frequency twice that of the two input fields.
thin film
A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
