Four new quasi-continuous wave (QCW) fiber lasers, YLR-X/YQCW-AC, are designed to replace flash lamp-pumped long-pulse YAG lasers. They feature peak pulse powers of 750, 1500, 3000, and 5000 W and energies from 7.5 to 50 J per pulse. Various options for the output fiber size are available. Applications include spot welding and drilling.

IPG Photonics’ New Line of Fiber Lasers

with High Pulse Energy

to Replace Flash Lamp-Pumped YAG

The Fiber Lasers are Cost-Effective for Spot Welding and Drilling

OXFORD, MA -- IPG Photonics Corporation, the world leader in high-power fiber lasers, announced today four new fiber lasers designed to replace flash lamp-pumped long pulse YAG lasers. IPG’s four new quasi continuous wave (QCW) fiber lasers feature peak pulse powers of 750 watts, 1,500 watts, 3,000 watts and 5,000 watts and energies from 7.5 joules to 50 joules per pulse. These air-cooled, compact units are substantially more cost-effective than conventional YAG lasers because of wall plug efficiencies greater than 30% and maintenance-free operation, in that there are no components that require replacement during ordinary operation over its useful life. IPG has begun shipments of the 750 watt and 1,500 watt peak power units with first shipments of the 3,000 watt and 5,000 watt units scheduled for the first quarter of 2010.

The YLR-X/Y-QCW-AC lasers offer outstanding pulse power and energy stability over the complete laser power dynamic range. IPG’s new QCW fiber lasers also have exceptional beam quality with various options for the output fiber size available and BPP as low as 0.35 mm x mrad (single-mode version) up to 2 mm x mrad. Convenient plug and play design and fiber delivery system continues to be standard as on all IPG fiber lasers.

“In the long pulse operation mode, the new laser is ideal for spot welding, seam welding and drilling,” said Dr. Valentin P. Gapontsev, CEO of IPG Photonics and a co-inventor of the laser line. “The CW mode of operation with power up to 500 watts allows fast cutting and makes these lasers a universal tool for many other applications. The laser covers a gap between our well known lines of nanopulsed lasers, covering the pulse duration range of 1 nsec to several µsec, and CW or high speed modulated series with an average power of 10 W to 50 kW. We believe that users will benefit from the many advantages of the modern QCW fiber over older flash lamp long pulsed YAG lasers that have a large share of the world laser market.”

These new fiber lasers are available for requalifying in existing lamp pumped processes at IPG’s application facilities in Oxford, MA, Santa Clara, CA, Detroit, MI, Burbach, Germany and IPG’s applications labs in China, Japan, Korea and Italy. Retrofit services, including engineers familiar with system integration, are available to help customers replace older production lasers with energy-efficient fiber lasers from IPG.
