II-VI Reports Laser Enterprise Unit Has Unveiled New Line of High Power Multi-Bar Stack Laser Diode Modules

II-VI Incorporated

II-VI Laser Enterprise GmbH, a global leader in semiconductor lasers, will debut its new expanded portfolio of high power multi-bar stack laser diode modules at Laser World of Photonics 2015 in Munich, Germany. This includes a new series of tap water cooled stacks for medical, pumping and defense applications, showcasing the industry's broadest wavelength range of high-power, high-brightness laser diodes enabling multi-kilowatt direct diode systems. The Tap Water Stack is a new QCW-style high reliability stack platform targeting high peak power and pulsed applications especially for the medical and defense markets. Key advantages are the use of industrial water instead of de-ionized water and the hard solder technology for die bonding. The use of industrial tap water not only reduces complexity of design for the cooling circuit; it eliminates the de-ionizer cartridge, as well as water resistivity and pH control which otherwise is required. By employing hard solder die bonding technology, this product is especially suitable for long-pulse on/off operation modes in the millisecond regime and not only microsecond operation. II-VI Laser Enterprise GmbH, offers the industry's broadest wavelength range of high-power, high-brightness laser diodes enabling multi-kilowatt direct diode systems. The company's high power laser diodes uniquely offer a wavelength range from 910 nm to 1070 nm, and are shipping in volume today to laser system manufacturers supplying the industrial, semiconductor, automotive, and materials processing markets. In addition to output power and brightness, covering the entire wavelength range from 910 nm to 1070 nm with consistent performance and reliability has become a critical factor to scale the power of kilowatt direct diode systems used for metal welding, cladding and cutting. II-VI Laser Enterprise offers up to 7 standard wavelength windows within the 910nm to 1070nm range with 150W and 250W power on micro-channel cooler or up to 120W on the industries smallest footprint passive mini cooler, enabling easy scaling of system power up to 40kW and beyond. For pumping applications >100W per bar are available in the 8xx nm wavelength range and in the eye-safe wavelength band around 1470 nm more than 50W have been demonstrated. II-VI Laser Enterprise laser diodes are the key technology in these high-performing laser systems because they deliver the required power, brightness and colors with industrial reliability. In 2013, II-VI Incorporated acquired the world class manufacturing site of GaAs semiconductor diodes in Zurich (Switzerland), and the associated product portfolios from Oclaro Inc. The business unit previously known as Oclaro Switzerland GmbH was renamed II-VI Laser Enterprise GmbH. II-VI Laser Enterprise sales engineers and technical support staff will be available for customer inquiries at Laser World of Photonics, Hall B1, Booth No. 403.
