Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Vienna University of Technology (TU Wien) have invented a new type of tunable semiconductor laser that shows smooth, reliable, wide-range wavelength tuning in a simple, chip-sized design.Tunable lasers are integral to many technologies, from high-speed telecommunications to medical diagnostics to safety inspections of gas pipelines. Yet laser technolo...

A project at Trinity College Dublin is now hosting Ireland's first BioBrillouin microscope instrument, applying Brillouin spectroscopy to life sciences and medicine.This should in particular enhance the College's research into cellular and tissue mechanics for the study of inflammation, cancer, and developmental biology.Brillouin microscopy offers a route to optical investigation of a biological sample's mechanical and viscoelastic properties, vi...

At last month’s LASER World of Photonics exhibition in Munich, Germany, industrial solutions and laser giant Trumpf presented a new materials processing laser system solution specified to improve welding processes.The system combines several sensors that monitor all process steps during laser welding. An integrated AI quality control system checks the weld seams, for example, and OCT (optical coherence tomography) monitors the welding depth of th...

Lawrence Livermore National Laboratory (LLNL) and the Extreme Light Infrastructure (ELI) European Research Infrastructure Consortium (ERIC) have announced that they have signed a new Memorandum of Understanding. This builds on their existing decade of strategic collaboration to advance high-power laser technology.“We are looking forward to expanding our existing collaborations with ELI on areas such as ultrabright high-repetition-rate sources for...

Physicists at the University of Oxford have unveiled a “pioneering” method for capturing the full structure of ultra-intense laser pulses in a single measurement. The breakthrough, a collaboration with Ludwig-Maximilian University of Munich and the Max Planck Institute for Quantum Optics, could revolutionize the ability to control light-matter interactions, say the team.The Oxford announcement states: “This would have transformative applications ...

Many materials emit light in ways that encode information in its polarization. According to researchers at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, polarization is key for future technologies, from quantum computers to secure communication and holographic displays.Among such phenomena is a form known as circularly polarized luminescence (CPL), a special type of light emission produced by chiral materials, in which light waves...

Tunoptix, a developer of computational meta-optics, based in Seattle, WA, has made what it calls “a breakthrough in mobile-scale spectral imaging”. The company’s latest meta-optical platform captures high-fidelity spectral signatures across the visible-to-NIR spectrum in a compact form factor smaller than 1 cm3, consuming less than 500 mW, and operating at real-time frame rates.Tunoptix’s ultra-compact hyperspectral imaging module.The company s...

Around 1,400 exhibitors and 44,000 visitors created “optimistic atmosphere”, says Messe München.Laser World of Photonics 2025 in Munich, Germany, came to a close on Friday, having set a new record for number of exhibitors and new innovations, said the organizer Messe München. Last week, 1,398 exhibitors from 41 countries presented the full spectrum of photonic technologies to around 44,000 visitors at the world’s leading trade fair. Trending to...

 China's laser industry began in the 1980s, when the first private laser enterprise, Chutian Industrial Laser, was founded in 1985 by Sun Wen, an alumnus of Huazhong University of Science and Technology. In the 1990s, some young people with dreams began to make their mark in the laser industry. In 1995, Gao Yunfeng, 29, rented an apartment in Huaqiangbei with a deposit of 400,000 Hong Kong dollars given by a German client. It took him three mont...

HSG Laser unveiled its next-generation laser cutting solutions—the GH V2.0 high-power flatbed system and TS2 intelligent tube cutting machine—at its Düsseldorf showroom, marking a major milestone in its European market expansion. (Image: HSG Laser)Attended by customers and partners from across the continent, the event featured live demonstrations of both systems and highlighted HSG’s growing infrastructure to support European manufacturers wi...

On June 24-27, 2025, the global optoelectronic event Laser World of Photonics 2025 was grandly opened in Munich, Germany. This exhibition brings together over 1350 companies from 43 countries, making it the largest in history. Among them, international laser giants Coherent, IPG, TRUMPF, and MKS showcased their latest breakthroughs and future directions in laser technology with multiple heavyweight new products.Coherent's New Product Debut: "Ful...
