LASER World of PHOTONICS CHINA: Setting the stage for the future with a new strategic direction and key photonic technologies
At Asia’s leading photonics trade fair, Jenoptik will be demonstrating its service spectrum, from single components through to highly complex systems for biophotonics, industry and semiconductor manufacturing.
As an international OEM partner for customer-specific solutions from concept creation through to series production the new Jenoptik Light & Optics division focuses primarily on supplying advanced photonics solutions. With decades of experience, customers rely on Jenoptik for cutting-edge, custom solutions based on an even broader portfolio of technologies, from optics, micro-optics, lasers, digital imaging, opto-electronics and sensors.
Jenoptik will be providing at LASER World of PHOTONICS CHINA an overview of its key photonic technologies, which are being used to successfully address future challenges in bioimaging, laser-based therapy, industry and semiconductor manufacturing. These include for example its modular imaging platform JENOPTIK SYIONS, compact laser beam sources for hair removal and dermatological applications as well as high-performance technologies for the mobility and industrial automation sectors.
In addition, Jenoptik will be unveiling its latest innovations for laser material processing in the form of its advanced 1060 nanometer semiconductor lasers, new 275 watt high-power diode lasers and F-Theta lenses as well as a broad selection of its highly efficient micro-optics.
Visit us from March 20-22, 2019 at LASER World of PHOTONICS CHINA, booth #W2-2440, in Shanghai.

Efficient semiconductor material for medical and industrial applications
Jenoptik has long established itself as a specialist in the complete process and technology chain for laser semiconductor materials, high-power diode lasers, solid-state lasers and customer-specific application solutions. The company’s production site in Berlin-Adlershof, Germany, produces robust and highly efficient bars, semi-bars and single emitters under the strictest quality controls. These products are individually tailored to perfectly suit customers’ specific requirements before they are further refined into high-power diode lasers in Jena, Germany, to be then delivered to customers all over the world.
With its advanced 1060 nanometer semiconductor lasers, Jenoptik facilitates reliable applications in the field of Healthcare & Life Sciences as well as for advanced manufacturing technologies. Its focus on the intensive and continual development of this semiconductor material is aimed at ensuring reliability in the long-term at high output power and for various applications. Jenoptik therefore provides its customers with the best support for implementing their individual laser solutions.
New diode laser with 275 Watt output for laser material processing
Jenoptik will also be presenting its latest development in the field of high-power laser sources for industrial material processing, and in particular for direct diode laser applications. The new diode laser with passive cooling impresses with its extremely high output power of 275 watts and long service life in both CW and hard pulse applications. This represents a significant increase in output power compared to products which had been available on the market up to now. Jenoptik has succeeded in combining important advancements in connection technology with an innovative approach to heat management to guarantee reliability under hard pulse conditions, even with such high output power.
The benefits are obvious: For manufacturers of laser systems in the kilowatt range, the complexity and costs of plants and systems are reduced due to fewer diode lasers being used. End users profit from both increased productivity and outstanding processing results thanks to the combination of high output power and excellent beam quality.
Visitors to LASER World of PHOTONICS CHINA can get the lowdown on the benefits of these high-power diode lasers before they go into series production in the near future.
New F-Theta lenses for additive laser production
Jenoptik has added two new lenses to the F-Theta-JENarTM Silverline lens series for high-power applications. With a focal length of 423 millimeters and a large scan field of 254 x 254 millimeters, the new lenses meet the requirements necessary for additive manufacturing processes such as 3D sintering.
They are designed for applications with fiber lasers from 1030 to 1080 nanometers and diode lasers from 900 to 1100 nanometers at outputs of up to 6 kilowatts. The high-quality materials and the low-absorption optical coatings (absorption is less than 5 ppm), ensure permanently stable beam quality with the highest spot performance.
In high-power application tests with lasers up to 6 kilowatts a minimum focus shift in fractions of the Rayleigh length was detected. These outstanding properties also ensure that production processes remain reliable and that the results will remain reproducible.
The F-Theta lens range from Jenoptik fulfills the requirements of almost all standard methods for micro and macro material laser processing. Jenoptik’s F-Theta series lenses are extremely robust and do not require additional cooling, even at high laser powers. The adhesive-free mounting technology also contributes to the long-term stability of high-performance optics, and also provides long-lasting investment security.
Pulse compression grating for 800 nm applications and beam combiner for diode lasers
In the field of optical gratings, Jenoptik is gradually expanding its portfolio for various wavelengths and applications. The company is introducing new encapsulated pulse compression gratings for 800 nanometer applications, including scientific setups in spectrometry, laser pumping, lithography, and inspection applications. The gratings are optimized in transmission and wavefront deformation, and reach an efficiency higher than 99 percent. The gratings remain thermally stable even at high powers. Thanks to the encapsulation, contamination can be easily eliminated. Jenoptik is set to introduce new enhanced efficiency beam for diode laser applications. In addition to the classic pulse compression in femtosecond lasers and laser material processing applications, the e² (efficiency-enhanced) gratings are designed for use in telecommunications.
Multifocus diffractive elements
Jenoptik offers its customers application-specific multifocus elements, for example with 3, 5, 7 or 9 spots. These allow fast and efficient laser cutting in different layers of the substrate simultaneously, because of the accurate separations and energy distribution between the different spots. The optical design of the multifocus elements allows for a wide range of applications through to 3D material processing.
Diffractive diffusers with large opening angle
Jenoptik diffusers allow an opening angle of more than 80 degrees. They are therefore particularly beneficial for sensor applications with LiDAR, or VR/AR applications, since they ensure a homogeneous beam over the entire scan field. This can be achieved with different angles in the X and Y direction and with a very high aspect ratio.
