New Laser and Optic Products Presented at Photonics West 2016

The Optical Systems division will present, amongst others, innovative freeform optics for infrared applications. The newly created Healthcare & Industry division will focus on highly efficient semiconductor material, diode lasers and a powerful femtosecond laser. In addition, Jenoptik will be showcasing optical, optoelectronic and laser solutions of both divisions at booth 1823 in South hall of the Moscone Center.

For 25 years, Jenoptik has been supplying worldwide markets with optical, optoelectronic and laser solutions. At the beginning of 2016, the Group introduced a new market-oriented division structure, realigning its business in three of its five divisions more closely towards the markets semiconductor equipment, medical technology and automotive served. Jenoptik President & CEO Michael Mertin: “This organizational change underscores the sustainable ongoing development of the Group to reflect customer requirements from our markets as well as global megatrends.”

In order to provide solutions for the fast growing healthcare and life science market, Jenoptik now bundles all healthcare technologies in a new Healthcare & Industry division. Jenoptik adds three new single emitters to its portfolio. The new products emit at a wavelength of 808 nm and can be used as pump sources of solid-state lasers with lower power, for diode direct and micro-marking applications, metrology and instrumentation, as well as for manufacturing of compact near infrared (NIR) light sources.

The power-scaled emitter chips have a cavity length of 2 and 4 mm and apertures of 95, 100, and 200 μm, all being based on TM-polarized material. Short-cavity devices have an output power of 4 W with a wall-plug efficiency of more than 60 %. Long-cavity devices with 100 μm-wide emitters run at 7 W and devices with 200 μm-wide emitters provide 10 W output power with wall-plug efficiencies of about 55 %. Furthermore, first results of working on 5-emitter bars operating at 40 W will be present.

Due to the extensive experience with femtosecond lasers Jenoptik has successfully transferred a new and challenging application into industrial production. Femtosecond pulses can now be used for scribing invisible pre-determined break lines that enable precise break loads in genuine leather with a natural inhomogeneous thickness between 1 and 2 mm.

The scribing process employs the powerful femtosecond lasers from Jenoptik’s JenLas femto series and prevents heat-induced swelling or other thermal damage of the leather. This is impossible to achieve with any longer pulsed lasers. Compared to conventional methods, such as mechanical knife scribing, the new manufacturing method enables much faster and more precise processing. All leather types and colors can be scribed with nearly the same process parameters.

The presented technological solution is particularly interesting for automotive applications, like airbag cover material or premium quality consumer goods. Jenoptik patented the leather-scribing method with a femtosecond laser and introduced a new generation of its laser perforation machine Votan A particularly for this process.

Since the beginning of 2014, Jenoptik’s Optical Systems division has been working together with seven other companies and two research institutes from the Thuringia photonics industry on the research project Freeform Optics Plus fo+ to develop innovative freeform optical systems. New design concepts are the focus of this work, as is the further development of production and integration technologies. The team’s objective is to optimize form factors, weight and costs in line with market requirements, but also to improve optical power and stability in the real boundary conditions found in potential areas of application.

Jenoptik has developed a demonstrator, with innovative freeform optics as the core element. It is designed for infrared applications, and will demonstrate the benefits of the technology developed for applications in the security, automotive and optical communications areas, for example. It will, moreover, also be possible to use the foundations laid as regards the design, production, and integration in areas beyond the infrared applications – for example, in laser materials processing or in semiconductor equipment.

Dirk Rothweiler, Head of the Optical Systems division, is positive in his assessment of these new possibilities: “The knowledge gained and technologies developed will enable us to address new target groups with efficient optical solutions, which require special form factor and weight standards, plus the cost-effective representation of volume scenarios. We will also be able to offer existing customers a higher level of solution expertise.”


Furthermore, Jenoptik continues the tradition of supporting young entrepreneurs participating in the SPIE Startup challenge, a competition of the international society for optics and photonics (SPIE). At this event, young entrepreneurs from the field of optical technologies will present their business ideas and products to an expert jury including Jenoptik employees Jay Kumler and Marc Himel.
