Lasers are the most versatile sources for materials processing. The flexibility to process wide range of materials and the advantages of using lasers over other conventional processes have made lasers the preferred choice for many material processing applications. Lasers have been well accepted in a wide range of industries from cutting fine intricate cardiovascular stents to drilling of guide vanes in aerospace industry to welding of thick steel for ship building industry.
Fiber lasers are versatile solid state lasers and offer the ultimate in solid state reliability and convenience. IPG offers the most powerful and the widest range of 1070 nm Ytterbium industrial lasers, including single-mode, multi-mode and Q-switch lasers. Lasers available from 1 W to 20 KW can support a wide range of applications for different industries.
Single-mode lasers with M2 < 1.1 are better suited for micro as well macro machining due to their ability to focus to the smallest of the spot sizes. The huge power densities associated with the small spot and good beam produce excellent cuts in thin and thick metals for cutting and deep penetrations for welding applications. Scribing ceramics and bending of HDD flexures for electronics industry, thin film removal for flat panel displays, engraving anilox rolls printing industry, thin sheet welding are few examples to mention.
Multi-mode lasers offers scalability of powers up to tens kilowatts, while still maintaining a very good beam quality. The wide range of applications with these lasers include cutting of thick automotive hydro form tubes, brazing of auto roof lines, welding of medical nails, heat treat industrial components, welding titanium panel for aerospace industry, deep penetration welding for ship building industry, clean cutting of thick stainless steels and aluminum and steel industries.
Q-switch fiber lasers offer unparalleled performance in laser marking applications in terms of marking quality, productivity and flexibility. The good beam quality and high peak power has also opened up unique applications such as high-speed hole drilling in silicon, and hybrid technology such as the laser-water jet. These lasers fit to a tee any marking requirements in metals, ceramics, most plastics and other materials.
Application Notes: IPG Photonics is continually developing new fiber laser technology, quite rapidly at times. New lasers with new capabilities allow previously unexplored applications and entirely new processing phenomena to be identified and studied. IPG’s Applications Facilities are striving to keep the laser industry up-to-date with Applications Notes that outline new process developments.
