MUNICH — TOPTICA Photonics TOPTICA Projects has successfully tested an experimental laser, jointly developed with the European Southern Observatory (ESO), MPB Communications (MPBC), and High Finesse, at the Allgäuer Volkssternwarte Ottobeuren observatory in Germany. The higher laser power and its chirping system will lead to significant improvements in the sharpness of astronomical images taken with ground-based telescopes, TOPTICA said, and the technology opens the door for developments in laser satellite communication. The laser will be installed at the European Space Agency’s (ESA) Optical Ground Station in Tenerife, Spain, in the frame of the ESO-ESA research and development collaboration.

MPBC developed the laser's 100 W CW 1178 nm, single-mode, single frequency, linearly polarized Raman fiber amplifier; the 100 W CW 1178 nm unit uses a two-stage polarization-maintaining (PM) RFA counter-pumped by a PM 1120-nm fiber laser to amplify a linearly-polarized 15-mW narrow-linewidth 1178 nm "seed" laser.

The full adaptive optics system will serve as a “guide star,” a type of laser that excites sodium atoms in Earth’s atmosphere to create an artificial star used as a reference point to correct blurring caused by atmospheric turbulence. The narrow-band highest optical-quality laser power of 63 W, locked to the sodium wavelength, is a leap forward compared to current astronomy laser technology, TOPTICA said. The experimental frequency chirping system is targeted to also improve the signal-to-noise of the system.

SEOUL, South Korea — Edmund Optics will relocate its regional South Korea office to a larger facility in the Mapo district of Seoul. The 264-sq-m (866-ft) office will facilitate enhanced services, a lab for specialized technical support, and easy access for visits. Under the leadership of Seheon Kim, the new facility will focus on support from skilled engineers, while also driving innovations and providing further expansion into additional markets, product lines, and services.

ADELAIDE, Australia — The University of South Australia (UniSA) was awarded a 1.8 million AUD ($1.3 million) contract with the federal government to develop technology that underpins the next generation of high-powered lasers in Australia for the defense and manufacturing sectors. David Lancaster, a UniSA professor of laser engineering, will lead the three-year project funded by the Defence Science and Technology Group in collaboration with the University of Adelaide. “High-powered lasers are increasingly being used in defense and manufacturing, but despite a long history of developing lasers in Australia, our technology is still relatively immature compared to other countries,” Lancaster said. As a result, Australia has had to buy from other countries, which, he said, is restrictive; most nations limit their exports of lasers. Lancaster specifically aims to build a new type of high-powered laser that combines multiple smaller lasers, fine-tuning the manufacturing process so it is cheaper and more efficient.
 
BLOOMINGTON, Minn. — Skywater Technology will work with Carillon Technologies to produce solid-state holographic optical beam steering (HOBS) chips for satellite and other free-space optical communications applications. HOBS technology was invented and is being developed for automotive lidar applications by Carillon partner Lumotive. In partnership with DARPA (Defense Advanced Research Projects Agency), Carillon is onshoring HOBS technology, standing up a complete design manufacturing, packaging, and test supply chain in the United States so the technology can be manufactured for commercial, space, and national security applications.

AMHERST, Mass. — The University of Massachusetts Amherst has received a $3.4 million grant to develop a portable optical sensor for the detection of brain injuries. The system, to be developed by a team led by Nianqiang Wu, consists of an ultrasensitive test strip and a portable optical reader to record the results. A drop of the victim’s blood from a finger prick is applied to the test strip and then fed into the diagnostic reader. Results will be supplied within 25 minutes, Wu estimated. The total direct and indirect costs for traumatic brain injuries treatment are estimated to be $60 billion annually in the U.S.

DUBLIN, Calif. — Adaptive high-performance lidar company AEye has partnered with Benchmark Electronics, a provider of engineering, design, and manufacturing services. Benchmark will ensure the quality and reliability of AEye’s 4Sight lidar sensors while rapidly scaling manufacturing to meet volume production needs. The partnership focuses specifically on manufacturing critical optical components and modules in AEye’s sensors targeted for a broad range of industrial markets.

KIRCHDORF, Sweden — Photolithography equipment and services provider Eulitha and semiconductor and advanced technology manufacturer VDL ETG will increase their cooperation in the manufacturing of photolithography equipment. The cooperation targets further development and manufacturing of state-of-the-art tools for high-volume manufacturing of photonic components such as AR/VR waveguides.

CAMBRIDGE, England — Life science equipment company Ziath has opened a new office near Maastricht, Netherlands. The office will be headed by Wilbert Lennartz, who seeks to further expand Ziath’s coverage with direct sales and knowledgeable support to customers across the Benelux region and northern France. The office will be able to accept and process orders and payments with efficiency and lower costs for a post-Brexit market. The office began operations Sept. 1.

NEW BRITAIN, Conn. — MicroCare LLC, a supplier of cleaning fluids and materials used in fiber optics, electronics, medical device manufacturing, and metal finishing markets, has acquired Certol International, a Denver-based manufacturer of specialty cleaning and disinfecting products to the medical, dental, and consumer marketplaces. The acquisition will strengthen MicroCare’s position in high-growth areas such as fiber optics, automotive, medical, and electronics.

GLOSSARY
photolithography
A lithographic technique using an image produced by photography for printing on a print-nonprint, sectioned surface.
lidar
An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
machine vision
Interpretation of an image of an object or scene through the use of optical noncontact sensing mechanisms for the purpose of obtaining information and/or controlling machines or processes.
