II-VI Debuts 1.5W 1060nm Seed Laser

40 percent more pulsed power targets next generation of fibre laser systems

The II-VI Laser Enterprise Division of II-VI, a provider of high-power semiconductor laser components, has unveiled a new generation of high power 1060nm single-mode laser diode seed module.

The new laser diode module is designed to seed nanosecond pulsed fibre lasers addressing the fast-growing market for MOPA (master oscillator power amplifier) fibre lasers. The innovative module delivers up to 1.5W in nanosecond pulse operations.

"With 40 percent more pulse power compared to our previous offering, our new diode seed module enables the next generation fibre laser systems for a wide range of applications," said Karlheinz Gulden, general manager, II-VI Laser Enterprise. "Together with our distributed feedback laser diode module designed for sub-nanosecond operations, we offer customers the most comprehensive seed laser diode portfolio in the market."

The II-VI laser diode seed module features a higher power 1060nm Fabry-Perot single-mode laser diode chip and a standard cooled telecom 10-pin mini butterfly type package that includes a thermistor and back-facet monitor photodiode. 

The 75 percent smaller form factor of the mini butterfly package versus the legacy 14-pin version enables a reduction of overall footprint of the seed assembly. A broad- or narrow-band Fiber Bragg Grating is optionally available to control the spectral properties for the suppression of Stimulated Brillouin Scattering (SBS) or for the improvement of frequency conversion performance, respectively.

II-VI Laser Enterprise will showcase the new laser diode seed module at SPIE Photonics West, Feb. 16-18, 2016, in San Francisco, CA.

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.
