II-VI Introduces high power Collimated Laser Bars


Modular assemblies can be integrated into direct diode lasers and diode-pumped solid state lasers

II-VI, a maker of high power semiconductor lasers, has announced the introduction of its high power laser bars and semi-framed stacks mounted with micro-optic collimator lenses, offering customers cost-effective modular assemblies that have high performance and reliability and can be easily integrated into direct diode lasers and diode-pumped solid state (DPSS) lasers.

Direct diode and DPSS lasers are increasingly the tools of choice for a wide range of materials processing, biomedical, and defence applications, due to their compact form factor, high power short-pulsed operation, and availability over a broad range of wavelengths from near-infrared to ultraviolet.

The performance, quality, reliability, and cost of these systems are highly dependent on those of their semiconductor laser sub-assemblies. II-VI says that it now combines its high power laser bars and new simplified semi-framed stack structures with fully automated optical alignment processes to deliver modular assemblies at optimal cost.

"Our laser bars feature a proprietary hard solder technology that withstands high power pulsed operation with field-proven reliability,ˇ said Chris Koeppen, vice president of II-VI Industrial Laser Group. "We now efficiently deliver optimal custom designs by leveraging the automated assembly processes in our direct diode manufacturing lines. These processes enable a variety of micro-optics, such as collimator lenses and volume Bragg gratings, to be cost-effectively mounted and precisely aligned to a broad range of customer-defined stack geometries.ˇ

II-VI will exhibit its portfolio of products at Laser World of Photonics, Munich, June 24 to 27 2019.
