II-VI Laser Enterprise Expands Its Laser Stack Product Portfolio to 14xx and 10xx nm at Photonics West 2014

ZURICH, Switzerland, Jan. 30, 2014 (GLOBE NEWSWIRE) -- II-VI Laser Enterprise GmbH, a subsidiary of II-VI Incorporated (Nasdaq:IIVI) and a global leader in semiconductor lasers, will debut new products from its expanded portfolio of high power Multi-Bar Stack laser diode modules at Photonics West 2014. This includes a wavelength extension to14xx nm and 10xx nm, targeting industrial applications such as plastic and metal welding and medical applications including acne treatment, skin rejuvenation and surgery.

Leveraging the latest advancement in chip technology, the multi-bar modules deliver higher output power and superior power conversion efficiency at 14xx and 10xx nm wavelength with proven reliability.

At 1440nm wavelength, CW output powers of 50W and 70W from passively cooled and actively cooled bars respectively have been demonstrated. In a stacked configuration, 300W of CW output power can be achieved with industry leading power conversion efficiency of > 35%, thereby significantly reducing cooling power requirements and paving the path for new applications in the 14xx nm regime.

At 10xx nm wavelength, > 250W CW output power from a mounted bar has been demonstrated with a power conversion efficiency of > 60%. As a result, up to Kilowatt power levels can be achieved by stacking the bars in a compact and reliable package.

The latest 14xx nm and 10xx nm stacks are available in the same compact framed or frameless stack configurations as existing 8xx nm and 9xx nm stack products. Multi-bar modules or stacks can be customized for output power and beam profile through lensing options.

"The latest introduction of new stack products underscores our ability to continuously advance our chip technology and expand the application space for laser diodes" said Product Line Manager, Larry Shi. "As a vertically integrated laser diode supplier, we can optimize our chip and packaging design to address the growing power and efficiency demands of the industry."
