The researchers used indirect OLED pumping to power the laser. They built an integrated device structure that efficiently coupled an OLED that had very high light output with a polymer-based, distributed feedback laser.

Most organic semiconductor lasers are optically pumped by another laser — a complicated, expensive process. Electrical pumping, which involves injecting a current to generate a population inversion, is challenging to achieve in organic...]]> https://www.photonics.com/Articles/OLEDs_Could_Be_Solution_to_Electrically_Driven/a69376 A69376 Fri, 06 Oct 2023 07:00:00 GMT
The Science and Technology Facilities Council (STFC) Central Laser Facility (CLF) was awarded £85 million ($103.2 million) by UK Research and Innovation for an upgrade initiative that includes construction of the Vulcan 20-20 laser, which is set to be the most powerful laser in the world.

Terahertz (THz) waves can be used to probe the magnetic properties of new materials. Efficient THz wave generation could advance applications in energy harvesting, ultrafast electronics, and THz spectroscopy.

Bright, coherent THz light sources can be achieved via high-frequency, high-density charge currents. It is possible to produce strong current density that is several orders of magnitude higher than what is typically found in electronic devices, by exciting nanometer-scale, metallic interfaces with femtosecond laser pulses.

To harness the power of high-density charge currents for generating THz waves, researchers at Fudan University, Shanghai Research Center for Quantum Sciences, and Beijing Normal University developed an...]]> https://www.photonics.com/Articles/THz_Generation_Technique_Could_Transform_Field_of/a69368 A69368 Tue, 03 Oct 2023 07:00:00 GMT
Postpartum hemorrhage, the leading and most preventable cause of maternal mortality, can be hard to detect, because physiological compensation mechanisms can mask excessive bleeding. In the early stages of hemorrhage, the sympathetic nervous system becomes activated to ensure adequate perfusion of vital organs and, in turn, vital signs remain stable.

Worldwide, the most common methods of diagnosing postpartum hemorrhage are visual estimation of blood loss or monitoring of vital signs. Blood loss is routinely underestimated beyond the point of early intervention.

To diagnose postpartum hemorrhage in its early stages, a multidisciplinary research team at Washington University in St. Louis developed a wearable optical device that...]]> https://www.photonics.com/Articles/Wearable_Sensor_Could_Lower_Mortality_Due_to/a69365 A69365 Tue, 03 Oct 2023 07:00:00 GMT
Policymakers and appointed officials outlined many of the U.S. government’s foremost priorities in science and technology, joining with leaders from the photonics sector in Washington, D.C., last week for the second SPIE Photonics Industry Summit. The one-day summit placed a premium on using industry collaboration to help spur economic and technological advancement, with additional focus on workforce development and education.

The event built on last year’s inaugural Industry Summit, which SPIE held six weeks after the CHIPS and Science Act was signed into law.

In 2000, Berthold Leibinger, the man who brought laser technology into Germany’s TRUMPF Group, established the Innovation Award — expressed in native German as the “Innovationspreis” — to honor outstanding R&D in the field of laser technology. Next to this prestigious award, the Berthold Leibinger Zukunftspreis was added in 2006 to recognize scientists driving fundamental laser research to new heights.

Leibinger sadly passed away a few weeks after the Innovationspreis ceremony in 2018, but he had handed the company over to his children years before, along with the Berthold Leibinger Foundation and its associated awards.

At the 2023 ceremony, held on September 22 in Ditzingen, the Foundation...]]> https://www.photonics.com/Articles/Berthold_Leibinger_Awards_Honor_Laser_Research_at/a69354 A69354 Tue, 26 Sep 2023 09:45:00 GMT
The University of Rochester has received nearly $18 million from the National Science Foundation (NSF) to design and prototype key technologies for EP-OPAL, a new facility dedicated to the study of ultrahigh-intensity laser-matter interactions. The facility could be built at the Laboratory for Laser Energetics (LLE) upon completion of the design project, according to the university.

High-intensity lasers enable scientific work in fields ranging from plasma science to particle acceleration, laboratory astrophysics to laser-driven nuclear physics — work that has resulted in myriad scientific, medical, commercial, and industrial applications.

Researchers at Chalmers University have developed a method to make microcombs 10 times more efficient, opening pathways to discovery in space and health care, and paving the way for high-performance lasers in a range of technologies. The team has established a company to commercialize the new technology.

Laser frequency combs can measure frequency with extreme levels of precision, analogous to a ruler made of light. The principle is based on a laser sending photons that circulate within a small cavity — a so-called microresonator — where the light is divided into a wide range of frequencies. These frequencies are precisely positioned in relation to each other, like the markings on a ruler. Therefore, a new kind of light...]]> https://www.photonics.com/Articles/More_Efficient_Microcombs_on_Road_to/a69347 A69347 Mon, 25 Sep 2023 07:00:00 GMT
SLAC National Accelerator Laboratory reported that the Linac Coherent Light Source (LCLS) x-ray free-electron laser (XFEL) has produced its first x-rays following a $1.1 billion upgrade. The improvements, more than 10 years in the making, allow the laser to fire up to a million x-ray flashes per second, which is 8000 times more than its predecessor. The generated, almost-continuous x-ray beam will be 10,000 times brighter than its predecessor on average.

LCLS-II will enable researchers to explore the details of quantum materials with unprecedented resolution to drive new forms of computing and communications; reveal unpredictable and fleeting chemical events relevant to sustainable energy; study how biological molecules carry out...]]> https://www.photonics.com/Articles/SLACs_Upgraded_XFEL_Registers_First_Light/a69343 A69343 Thu, 21 Sep 2023 07:00:00 GMT

The ability to measure the size and color of the light at the same time could improve a crucial step in chipmaking — lithography — by enabling lithography machines to make smaller, faster chips. To produce the microsize chips used in most electronic devices, lithography machines need precision-engineered lenses, mirrors, and light sources.

A multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical resolution photoacoustic imaging.

By providing an exceptionally high level of sensitivity, SLD-PAM could help broaden the use of photoacoustic microscopy in biomedical applications. In the future, it could translate to clinical settings; for example, it could be used for ophthalmic exams where a low-power laser is preferred for the patient’s safety and comfort. Long-term monitoring of pharmacokinetics or blood flow also requires low-dose imaging to alleviate perturbation to tissue function.
