II-VI launches red lasers for workpiece alignment in multi-kilowatt fiber-laser systems

Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has launched red lasers for workpiece alignment in multi-kilowatt fiber laser systems.

Red lasers integrated into high-power fiber-laser systems allow precise alignment of multi-kilowatt infrared laser beams to the target process areas and must operate in the presence of very high back-reflections from the workpiece. The new red lasers can maintain a tightly controlled high output power of 350mW to within 2% while under the presence of up to 5W of reflected optical power. The design ensures a controlled and reliable process in applications such as welding, cutting, brazing and laser additive manufacturing.

“Leveraging our core competency in high-power semiconductor laser packaging, this red laser adds innovative optics that enable its unique performance in output power stability,” says Chris Koeppen, VP of the II-VI Industrial Laser Group. “Our new red laser improves process performance and reduces down-time and maintenance cost of multi-kilowatt fiber laser systems.”

II-VI is showcasing its portfolio of engineered materials, lasers and optics for materials processing, life sciences, consumer electronics and automotive applications at the following conferences:

SPIE BIOS Expo 2019 (booth #8543) in San Francisco, CA (2-3 February), on biomedical optics;
SPIE Photonics West 2019 (booth #1840) in San Francisco, CA (5-7 February) on photonics; and
EALA - European Automotive Laser Applications 2019 (booth #3) in Bad Nauheim, Germany (12-13 February) on laser-based processes for future car body productions.
