compact microsystem light source
Miniaturised laser systems for the visible spectral range
Hybrid diode laser systems are creating a market for numerous new semiconductor laser system applications, for example in medical systems, material processing and the entertainment sector. These systems incorporate a host of functions in a space the size of a matchbox, making it possible to create even more compact and portable solutions while retaining the same performance. At Laser Optics Berlin 2010 the institute is exhibiting these powerful, light-intensive hybrid laser sources, which using micro-optics and crystals have been developed for the visible spectral range (red, green and blue). The institute has succeeded in raising the optical output of the laser module to the 1 W mark with a wavelength of 488 nm when in constant use at room temperature. This concept can be implemented quickly and easily using different wavelengths. The institute is also exhibiting a pulse picker for ultra short light pulses, as well as highly efficient, ultra narrow band diode lasers.

Light Modulator for Broad Wavelengths
Light Modulator PLUTO-NIR-2
Holoeye has developed an additional version to supplement the currently available PLUTO Light Modulator Systems. The PLUTO-NIR-2 (picture) is optimized for the 800nm wavelength. This enables efficient implementation in fs-laser (Ti:Sa) and biophotonics applications. The essential technical data: 700-900nm wavelength, 8.0µm Pixel Pitch, 1,920 x 1,080 Resolution and 60Hz Frame Rate via DVI. All PLUTO-SLM versions are now delivered with an extended software package, which includes a program for “real-time” hologram calculation, e.g. for optical tweezers or holographic projection; the calculations are conducted directly on the GPU of the graphics card. Furthermore, a LabView SubVi for simple addressing of optical functions has been added. This can be implemented directly in user-defined Lab-View programs, e.g. for “closed loop” applications.

Non-Invasive Laser Diagnostics
Diagnostics Device LIMES 16-P
LTB Lasertechnik Berlin has developed a non-invasive diagnostic investigation based on the LIMES 16-P (picture), a device used for the early detection of black skin cancers. The new diagnostics provide an additional feature: the ability to differentiate between cancer and a hematoma under a fingernail or toenail. The diagnostics do not affect the nail. The successful trial took place recently with Dr. med. Reinhold Eichhorn’s dermatology practice in Berlin. The LIMES 16-P verification system for melanoma diagnostics is based on a newly patented process which makes it possible to measure the ultra-weak fluorescence of melanin in dermal tissue. There is a great difference in the fluorescence of tissue with healthy pigmentation and that of tissue of a malignant melanoma. Thanks to the LIMES 16-P-s high localized resolution, the degeneration of the tissue can be detected in very early stages. At the same time, the process helps avoid unnecessary biopsies.

short-pulse semiconductor disc laser
Semi-conductor lasers for terahertz spectrometers
This company is exhibiting a fully semiconductor-based light source which can produce laser pulses for a duration of less than 200 fs at its stand. The pulse repetition rate of this mode-coupled disc laser (image) is in the GHz range. This is ideal for terahertz spectrometers using asynchronous optical sampling (ASOPS). In cooperation with the University of Constance the laser was put to successful use for this very purpose. This compact short pulse light source also can also be used as a seed laser for fibre amplifiers and trapezoid diode amplifiers. It is thus possible to create femtosecond pulse sources for spectroscopic purposes and to process micromaterial easily and at low cost. The laser resonator consists of only three elements (a gain chip, a saturable absorber mirror and decoupler) and requires no dispersion compensation elements, which for a femtosecond laser is unique. The exhibit on display has a laser wavelength of 1,040 nm, which can be adjusted for a wide spectral range.

Fiber-Laser with Narrow Line Width
Until now, Optoprim was primarily specialized in optical measurement technology instruments, like spectrometers, interferometers and polarimeters. At Laser Optics Berlin 2010 the distributor will present several new types of lasers for optical components and systems. One example is the “Slow Light Laser” with the narrowest line width on the market. This unique fiber laser will be employed in interferometry and remote sensing applications like LIDAR. Another notable development is the Single-Mode-Laser Diode with an integrated holographic lattice in the diode housing. In applications which require lattice-stabilized diode lasers, this reduces costs, space and work. There is also a broad range of short-pulse lasers: Optoprim offers not only Ti:Sapphire lasers but also Ytterbium, Erbium and even amplified short-pulse diode lasers, thereby covering the entire pulse duration spectrum from 10fs to 1ns.

piezo-ultrasound motors for its latest generation of Totalstations
Precise positioning for optical technology
Metrology, production and medical equipment – the extremely precise alignment of components is essential for today’s optical and laser technologies. The company, based in Karlsruhe, is presenting its latest nano-positioning systems and piezo-motor drives at Laser Optics Berlin 2010. Working together with Leica Geosystems AG this exhibitor has developed a piezo-ceramic motor for its latest generation of Totalstations (Fig.). The aim was to significantly reduce measurement times through faster motion and improved start/stop action. Within a tiny space the PILine piezo-ultrasound motors rotate the measuring head around a horizontal and a vertical axis. The motors used in the new Totalstations offer increased acceleration, high speeds of at least 180 degrees per second (four times the usual speed up until now) and precise initial movement of the instrument and the telescope. This enables them to combine the most accurate measurements of angles and distances with substantially improved automation of the measurement processes.

Nano Vibration Analyzer
Measuring the oscillations in micro-structures
This company, from Ilmenau, is presenting a faser-coupled laser interferometric vibrometer (Fig) which is incorporated in a technical microscope at Laser Optics Berlin 2010. This is ideal for measuring dynamic responses and the static deflection of microstructures, MEMS and cantilevers. The object to be measured can be positioned and scanned across a wide range from 50 mm by 50 mm or 100 mm by 50 mm with the aid of an x-y table and can be observed using a USB camera. The microscope has a replaceable lens. Ten and 50-fold magnification are possible. If the 50x lens is used the laser spot diameter is less than 2 µm. The resolution of 0.1 nm that can be achieved by the laser interferometric vibrometer is in the subnanometer range, enabling oscillations of up to 2 MHz to be analysed. Special software has been developed to register and display the data readings. In addition to an analysis of the frequency oscillations and of the triggered readings this also permits script-controlled sensoring of surface structures.

Spetec cleanroom workbench
Portable workbench for cleanrooms
Based in Erdingen, this company is exhibiting a new product for cleanrooms, in addition to its cleanroom cell and the Laminar Flow Box. The Spetec cleanroom workbench (image) rounds off the existing range of products and can be tailored to customers’ specifications. In terms of size and equipment it can be manufactured to specific requirements. As a rule it is made using cleanroom-compatible alloy sections. The side walls consist either of glass, acrylic glass, alternatively the box is surrounded by a PVC strip curtain. A Laminar Flow module is then mounted on top so that conditions inside the box fulfil cleanroom class 5, which is equal to only roughly 100 particles measuring 0.15 µm. Compared with the one million particles present in an everyday office or laboratory this represents a ten-thousandfold improvement in air quality. The principal uses of the Spetec cleanroom workbench are in chemical analysis, assembling optical and mechanical components, the semiconductor industry, laser research and plastics engineering.

portable mini goniometer
Measuring the exact angular distribution of colour emitted by LEDs
The newly developed Imaging Sphere System IS TE from Radiant Imaging targets the market for quality control in the manufacturing of LEDs and small light sources. It measures the angular distribution of light density and colour, and makes it possible to quickly and accurately analyse LEDs supplied to and by the company. The company is exhibiting the Imaging Sphere System IS TE at Laser Optics Berlin 2010. This portable mini goniometer (image) measures the exact angular distribution of the colour and light density of small light sources such as LEDs in a matter of seconds. It is often difficult to define light emission properties, which is why this device offers practical assistance both in manufacturing and inspecting incoming components. The detector comprises a CCD camera with CIE-adjusted calibrated colour filters. It is partly enclosed within a box and measures light distribution. The system not only occupies less space than a conventional goniometer but also saves costs.

Flame monitoring and checking exposure to UV light
This college is presenting one of its main areas of teaching and research, optical technologies, at Laser Optics Berlin 2010. The emphasis is on two applied research and development projects and the masters course in photonics. Together with its partner in the field, sglux SolGel Technologies GmbH, the team is developing new types of photodiode chips for the ultraviolet spectral range. Such electronic construction elements are suitable, for example, for flame monitoring in heating systems and for checking on water disinfection plants that operate with UV light. A UV measuring unit is also being developed for “sun-seekers”, enabling sunbathers to determine their own level of exposure. Another research project concerns the rapid transfer of data in telecommunications. Specially selected organic materials are used to produce electro-optical modulators, which enable electronic information to be superimposed on optical carrier signals. The four-semester masters course in photonics is intended to meet the growing demand for qualified staff in the optical industry.

PHAROS femtosecond laser
High performance femtosecond laser with variable pulse length
The amplifier system on the new PHAROS femtosecond laser (fig.) produces pulse energies of up to 1 mJ and has an output of up to 10 W. The pulse duration is variable and can be adjusted from 180 fs to 10 ps. On standard models the repetition rate ranges from a single shot to 600 kHz, but can also be increased to 1 MHz. The laser parameters can be easily set using a touchscreen pad or a PC with an USB interface. Each module in this system is temperature-stabilised and hermetically sealed, thus enabling the laser to also be used under industry conditions and in non-air conditioned rooms. The system is of robust and compact design with a laser casing measuring just 60 x 36 x 21 cm³. The PHAROS is also suitable for downstream connection of an OPA/NOPA system (“Orpheus“) if required, enabling an adjustable fs light source to be obtained. Ease of operation and excellent stability make this laser suitable for industrial applications in the processing of materials. Its range of uses can also be expanded, enabling this laser to be used in many scientific applications.
