II-VI Laser Enterprise Introduces New High Power Laser Diode Modules

Portfolio includes tap water cooled stacks for medical, pumping and defence applications

II-VI Laser Enterprise, a German developer of 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 defence applications, showcasing what are claimed to be 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's high power laser diodes 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 2013, II-VI acquired the manufacturing site of GaAs semiconductor diodes in Zurich, Switzerland, and the associated product portfolios from Oclaro. The business unit previously known as Oclaro Switzerland GmbH was renamed II-VI Laser Enterprise GmbH.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
