II-VI launches 120W pump laser modules with wavelength-stabilized output for ultrafast fiber lasers

Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has launched 976nm pump laser modules with up to 120W of wavelength-stabilized output power.

Wavelength-stabilized pump laser modules enable ultrafast fiber lasers to operate with very short pulses for high-precision drilling and marking. II-VI’s pump laser modules achieve 120W of output power while precisely maintaining a wavelength of 976nm over a wide operating temperature range. Their high power enables fiber lasers to be designed with fewer pump laser modules, lowering laser system cost. Their precise wavelength stability lowers the warm-up time and maintenance of laser systems, improving productivity, says the firm.

“This wavelength-stabilized module achieves 50% more output power than that which we introduced only four months ago, demonstrating our rapid technology advances,” says Chris Koeppen, VP of II-VI Industrial Laser Group. “Our vertically integrated modules leverage both the reliability of our gallium arsenide semiconductor laser platform and our state-of-the-art spatial beam combining technology to achieve high efficiency and wavelength-stabilized output powers over an industry-leading operating temperature range of 20-45°C,” he adds.

II-VI’s wavelength-stabilized pump laser modules are available over a wide range of power levels of 15-120W coupled to industry-standard 106.5µm core fiber. II-VI’s broad portfolio of components for fiber lasers includes seed lasers, acousto-optic modulators, pump and fiber-laser combiners, as well as micro-optics for high-power isolators.

In booth #117 (Hall A2) at Laser World of Photonics 2019 in Munich, Germany (24–27 June), II-VI is exhibiting its portfolio of merchant products for all laser technology platforms employed in high-power or precision materials processing. From ultraviolet to the far-infrared, II-VI’s laser optics are on display along with new products for fiber lasers as well as laser heads and beam delivery solutions. In the life sciences area, II-VI’s display consists of spectroscopy optics, flow cells and precision temperature-controlled modules to support advances such as in DNA sequencing. II-VI is also showing products from epitaxial wafers to semiconductor lasers that can enable new features such as 3D sensing in the next generation of consumer electronics.
