LZH for the 10th Time at Photonics West: space lasers, fiber optics, single frequency lasers, ultrashort pulse lasers

23.01.2014
This year will be the tenth time the LZH has been an exhibitor at the German Pavilion at the fair Photonics West (San Francisco, USA; 4-6 February 2014).

The Laser Development Department of the LZH will be presenting systems and components from the fields of space lasers, fiber optics, single frequency lasers and ultrashort pulse lasers in North Hall at stand 4601.


The new MOMA prototype model.

Since the first German Pavilion at Photonics West in 2004, it has developed into the largest stand there, presently with 58 exhibitors, and is certainly a crowd puller for visitors from all over the world. The organizers of the most important fair for lasers and photonics are expecting around 20,000 visitors and over 1,200 exhibitors.

Fresh from the labs: The new prototype of the MOMA-APM laser head for the Exomars Mission 2018

An important step in the preparations for looking for traces of organic substances on Mars during the Exomars Mission 2018 has been taken. The fundamental design of a flight model of a diode-pumped, Q-switched laser which emits nanosecond pulses in the UV range at a wavelength of 266 nm in outer space has been developed for the new prototype of the MOMA-APM laser head (Mars Organic Molecule Analyzers Advanced Prototype Model). This laser head, which was developed by the Space Technologies Group, will be used as the excitation source in the laser desorption mass spectrometer of the MOMA system, and it generates ions from organic molecules which cannot be vaporized. The ions can then examined in the MOMA mass spectrometer.

Premier at the fair: A wavelength multiplexer for 633 and 1550 nm

The Fiber Optics Group is presenting the newest fiber components and integrated fiber amplifiers, among which is a coupler for monomode fibers, a pump light combiner, and a fiber cladding mode stripper for the wavelengths between 0.6 and 2.1 µm. For the first time, a wavelength multiplexer consisting of two different fibers will be shown, which combines the wavelengths of 633 nm and 1550 nm. Combining the light fields of different fibers opens new applications, for example in medical technology.

Also, a highly integrated, ytterbium-doped fiber amplifier will be shown, which was developed for the detection of gravitational waves using interferometry, and which has a line width of only a few kilohertz, an emission wavelength of 1064 nm and an average output of over 200 W. Further application fields for this prototype are coherent beam combinations, laser metrology, and investigations on quantum optical phenomena, and nonlinear optics.

Infrared laser with a wavelength of 1.95 µm for the microprocessing of Plastics

A result of the EU project IMPROV (Innovative Mid-infrared high Power source for Resonant ablation of Organic photoVoltaic devices; Grant Agreement No. 257893) will be presented by the Ultrafast Photonics Group, the third prototype of the IMPROV laser with a wavelength of 1.95 µm. By using very narrow band gratings, the laser produces laser pulse lengths between 250 and 550 ps, and has a high quality spectrum. The system is an excellent laser source for downstream fiber amplifiers, and the pulses can be amplified without pre-time-stretching in the fiber. First experiments show that energy in the µJ range could be reached with a single fiber amplifier. Based on polarization-maintaining fibers, the laser output is stable, even when there are external influences, such as temperature fluctuations. Due to the pulse parameters, this laser system is excellent for nonlinear frequency conversion in the mid-infrared spectral range. Laser pulses in this spectral range can be used to selectively process organic layers, for example for organic photovoltaic solar cells.

Fiber lasers for a free fall

The Single-Frequency Lasers Group is presenting a 2 µm thulium fiber laser system, which was especially developed for use under micro-gravitational conditions in a fall tower, and which must withstand continuous dropping and impact from a height of 100 m. As commissioned by the Center of Applied Space Technology and Microgravity (ZARM) in Bremen, the LZH has developed this system for the PRIMUS-II project for the investigation of the equivalence principle. The equivalence principle dates back to Galileo Galilei and states that all physical bodies, independent of their chemical composition, size, form and mass, fall in the same manner in a vacuum, if other forces are not present.

LZH-Spinoff neoLase GmbH

A further exhibitor at the German Pavilion is the neoLase GmbH, a spinoff from the LZH, which will be presenting their MOPA laser system, a highly brilliant pico- and nano-second laser and amplifier modules.

Im Focus: Self-assembling nano inks form conductive and transparent grids during imprint

Transparent electronics devices are present in today’s thin film displays, solar cells, and touchscreens. The future will bring flexible versions of such devices. Their production requires printable materials that are transparent and remain highly conductive even when deformed. Researchers at INM – Leibniz Institute for New Materials have combined a new self-assembling nano ink with an imprint process to create flexible conductive grids with a resolution below one micrometer.

To print the grids, an ink of gold nanowires is applied to a substrate. A structured stamp is pressed on the substrate and forces the ink into a pattern. “The...
