Lasers are the most versatile and controllable energy sources available to industry for processing materials. Lasers have become accepted across a wide range of industries, applications range from cutting intricate cardiovascular stents to drilling of guide vanes in the aerospace industry to welding of thick steels for ship building industry.

Fiber lasers offer the ultimate in solid state laser reliability and convenience. IPG offers by far the widest range of Ytterbium industrial fiber lasers, these include  single-mode, multi-mode, quasi-continuous wave (QCW) and Q-switched type fiber lasers. Lasers are available from 1W to >100 KW average power, the highest output power of any industrial laser of any type available today. These lasers support a wide range of applications in many different industries.

CW Lasers

Medium power (up to 1 kWsingle-mode fiber lasers with M2 < 1.1 are better suited for micromachining due to their ability to focus on the smallest spot sizes. The excellent beam quality of fiber lasers enables high quality narrow kerf width (< 15 mm) cuts in thin metals. Cutting stents and solder mask stencils were two of the earliest successful fiber laser applications. Scribing ceramics for the electronics industry and engraving anilox rolls for the printing industry are two better known examples.   Higher average power kW class fiber lasers are required for laser processing thicker materials at high speeds. Multi-mode lasers are preferred and average power is scalable up to tens of kilowatts. The wide range of applications for  these lasers include cutting of thick automotive hydroformed tubes, brazing of auto roof lines, deep penetration welding for ship building industry and clean cutting of thick stainless steels.

QCW Lasers

QCW lasers are an entirely new type of fiber laser developed by IPG to replace solid state flashlamp pumped lasers. This unique laser concept, exclusive to IPG, has now been extended into a complete range of pulsed lasers from 150 watts up to 2 kW average power and up to 20 kW peak power. This laser is a factor of 10 times more efficient than flashlamp lasers. It is available with a range of fiber diameters, from single mode to   200 μm and a range of QBH collimators so that a very wide range of focused spot diameters are available. It is rapidly replacing the older flashlamp technology for drilling, welding and cutting applications, in particular for medical device applications such as pacemakers.

Pulsed Lasers

Low power Q-switch nanosecond pulsed fiber lasers offer unparalleled performance in laser marking applications in terms of mark quality, productivity and flexibility. The combination beam quality and high peak power has also opened up unique applications such as high-speed hole drilling in silicon.   These lasers are well suited for most marking requirements in metals, ceramics and most plastics. High average power Q-switched type pulsed lasers, up to 5 kW, are also available, these lasers are used for rapid removal of paints and coatings over large surface areas.

Application Center

IPG Photonics is continually developing fiber laser technology with regular introductions of new lasers. New lasers bring with them new capabilities to 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.
