Laser Focus World (LFW) Innovators Awards 2022 has announced HARPIA-TG transient grating spectrometer and PHAROS-UP femtosecond laser among the best innovations of the year by gold and silver medals, respectively. The honorees were selected by an esteemed and experienced panel of judges from the optics and photonics community. HARPIA-TG HARPIA-TG transient grating spectrometer was announced as the … Continue reading
Working as part of the initial phases in the u-Care project, Professor John Travers and Research Associate Dr. Christian Brahms have developed a first-of-its-kind compact tunable high brightness laser that operates using optical soliton dynamics in gas-filled hollow capillary fibers. This part of the project aims to develop tunable ultrashort pulses of light in the … Continue reading
Tandem organic solar cells have drawn much attention in the field of solar energy. They consist of two monolithically connected cells enabling a broader absorption spectrum and efficient use of photon energy. In a Nature Communications article, entitled “High performance tandem organic solar cells via a strongly infrared-absorbing narrow bandgap acceptor,” researchers use the ultrafast … Continue reading
Light Conversion is happy to announce that the new 2021 product catalog “FEMTOSECOND LASER SYSTEMS FOR SCIENCE” is now available online. Here is an excerpt from the first page of the catalog: Founded in 1994 as a Vilnius University spin-off, LIGHT CONVERSION is now a major ultrafast laser technology company with over 300 employees, 10% … Continue reading
Researchers from the Polish Academy of Sciences, Lodz University of Technology, and the University of Warsaw use a PHAROS laser from Light Conversion to observe the surface-enhanced (SE) signal of water in an aqueous dispersion of silver nanoparticles. The observation techniques used were spontaneous Surface-Enhanced Raman Spectroscopy (SERS) and Surface-Enhanced Femtosecond Stimulated Raman Spectroscopy (SE-FSRS) processes. This work opens up exciting … Continue reading
Noble metal nanoparticles patterned in ordered arrays interact and generate plasmonic surface lattice resonances. Up to now, the assumption was that such nanoparticles are static. But researchers from the Kaunas University of Technology in Lithuania have demonstrated that this is not the case at ultrafast time scales. They used Transient Absorption Spectroscopy (TAS) to study … Continue reading
