Lasers work and split brittle materials
Among various solid state laser developments to be shown at LASER 2007 is a thermal laser beam separation process to split brittle materials such as glass, ceramics and semiconductors.
Immediately following this ceremony, the neighboring Ferdinand-Braun-Institut fur Hoechstfrequenztechnik (FBH) is officially opening its new laboratory rooms.
It is no coincidence that FBH und Jenoptik Diode Lab combined their facility-opening ceremonies, as this reflects many years of productive cooperation.
In fact, Jenoptik Diode Lab itself was founded in February 2002 as a 'spin-off' resulting from the close cooperative work between Jenoptik and FBH.

Abac acquires ALUP Kompressoren
As part of a strategic investment in the European industrial market, ABAC, the world's largest manufacturer of compressed air systems, has acquired ALUP Kompressoren GmbH.
The new company is an excellent example for successful know-how and technology transfer, producing optoelectronic semiconductor components for diode lasers, based on research conducted by the Ferdinand-Braun-Institut.
At the new facility, the company will, in a process common to semiconductor production, structure 3in gallium arsenide wafers (GaAs) for later processing into high-performance diode lasers in Jena.
In addition to providing for its own production needs, Jenoptik will supply external customers with these laser bars as well.
The company will invest a total of around EUR 14 million in the project, with M+W Zander Gebaeudetechnik serving as general contractor.
40 new jobs will arise with the beginning of production in early summer 2006.
Diode Lab's new Berlin production facility will allow the Jenoptik Photonics Group to respond flexibly to the necessities of the market.
The Jenoptik subsidiary is well integrated into a widespread network of research facilities and innovative companies at Berlin-Adlershof.
The Berlin site was chosen chiefly due to its close proximity to FBH, the company's scientific partner, and since it is possible to expand production there whenever necessary.
* New output record: Successful symbiosis of research and industry - high-performance diode lasers are the most effective artificial sources of light today.
While the FBH conducts world-class research in this field, Jenoptik is one of only a few companies in the world that produces large quantities of state-of-the-art high-performance diode lasers with great reliability and in top quality.
Due to their close cooperative relationship, Jenoptik is able to rapidly translate FBH research into industrial production.
At the same time, Jenoptik also conducts its own additional research on technology specifically for industrial use.
Only a few days ago, Jenoptik was able to announce a new output record, as 454W were produced by a 10x2mm semiconductor bar.
Jenoptik Diode Lab supplied the semiconductor material for the bar.
As part of a research project, Jenoptik is currently testing the semiconductor bars of different providers for their maximum output, and for the capacity limits of the material, layers, assembly technology, and cooling systems involved.
High-performance diode lasers are used as pump sources for solid-state lasers, in materials processing, display technology, and in medical applications.
These diode lasers are advantageous in many respects with their high conversion-efficiency of electrical energy into light, their compact structure that allows for mass production, and their little drive-voltage.
Laser properties may be easily adapted to individual application, making this type of laser one of the most important for future development.
The particular performance of Jenoptik Diode Lab's laser diodes is a result of their high beam quality, narrow spectral line width, and high output power.
The Ferdinand-Braun-Institut develops and manufactures a wide variety of designs for high-brilliance diode lasers with complex structures, comprising a wide spectrum of wavelengths from 635 to 1200 nanometers.
* About Ferdinand-Braun-Institut fur Hoechstfrequenztechnik - the Ferdinand-Braun-Institut fur Hoechstfrequenztechnik (FBH Institute for high frequency technology - www.fbh-berlin.com) is one of the leading institutes for applied research in microwaves and optoelectronics.
Based on III-V semiconductors it manufactures high-frequency devices and circuits for communication and sensor technology as well as high-brilliance diode lasers for materials processing, laser technology, medical technology and high-precision metrology.
In order to assure rapid transfer of technology FBH works closely with partners and customers in industry and the scientific community.
The institute has a staff of 150 employees and a budget of 13 million euros.
It is part of the Forschungsverbund Berlin e.V.
(FVB) and is a member of the Leibniz Association.
* About Jenoptik Diode Lab - Jenoptik Diode Lab is a 100% subsidiary of Jenoptik Laserdiode within Jenoptik's Photonics business division.
Jenoptik Diode Lab was founded three years ago as a 'spin-off' of the Ferdinand-Braun-Institut fuer Hoechstfrequenztechnik in Berlin-Adlershof, and currently employs a staff of ten.
The company specialises in the production of semiconductor elements for use by Jenoptik Laserdiode in the development and production of high-performance diode lasers.
Sales in Jenoptik's Photonics business division increased to over 350 million euros in fiscal year 2004, and are expected to rise to between 385 and 400 million euros in 2005.
Some 2,600 employees work for the business division in its laser, high-performance optics, and sensorics units.
Jenoptik develops, manufactures and distributes photonics components, modules, system solutions, and entire facilities, always putting light to use as an industrial tool.
* Glossary: diode lasers, high-performance diode lasers - diode lasers can be found in nearly every household.
They are used in electronic entertainment systems and in personal computers, making it possible to access audio, image, and video data without a hitch.
These lasers are made of semiconductor materials and offer a great many advantages: They are small, energy-saving, and, compared to other types of lasers, excellently suitable for mass production, making them cost-effective as well.
When used in CD players, diode lasers show only a small fraction of their potential.
In spite of its small size a single FBH-laser emits up to 20W: 5000 times greater power than a laser in a CD-player.
Applications of these brilliant light sources are versatile, ranging from medicine to measurement to sensors.
When single lasers are combined into laser bars, they deliver an output power of up to 475W.
