OXFORD, Mass., May 5, 2014 — IPG Photonics Corp. saw a 15.4 percent increase in profits last quarter over the same period last year, powered by demand for high-power fiber lasers. The company reported earnings of $40.5 million compared to $35.1 million in the first quarter of 2013. “High-power fiber laser sales increased 33 percent and medium-power, QCW and laser systems sales also were up compared with the prior year,” said CEO Dr. Valentin Gapontsev. “Geographically, we saw strong growth in Europe, China and Turkey, and achieved record sales in Japan. North American sales were lower due to...Read full articleRelated content from Photonics MediaARTICLESIPG Announces Layoffs Following Q3 Earnings ReportIPG Photonics Corp., a maker of industrial lasers, announced this week that 300 positions will be eliminated from its global workforce.

The quasi-continuous wave for industrial applications further broadens fiber lasers’ appeal.The modern fiber laser is pumped by high-power, multimode single-emitter diodes or diode bars, typically through a cladding surrounding a single-mode core. This single-mode core is typically 5 to 12...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookLaser Measurement Systems: Best Practices: When purchasing a laser, learning how to apply, troubleshoot, and evaluate that device is very important.Given the pace at which technology advances, there always seems to be a learning curve.
