Recent #OPG_BOEx research defined the optimal imaging time put for fluorescence-lifetime-based tumor identification: https://bit.ly/4c6K0qc The VU Brussel and Universiteit Gent team investigated the in vivo time course of ICG in syngeneic tumor-bearing mice using a novel macroscopic fluorescence lifetime camera. They found that fluorescence lifetime imaging may provide higher accuracy in tumor identification than intensity-based imaging at a similar time point. #Biology #CancerResearch #ScienceAndTechnology

New research from #OPG_Optica demonstrates single-shot ultrafast terahertz near-field microscopy https://bit.ly/4c8LbW9 In this approach, researchers used an electro-optic sampling technique for terahertz near-field detection to effectively encode terahertz-captured microscopic dynamics at different times into a single superimposed optical image. The technique lays the groundwork for exploring ultrafast, non-repeatable, or irreversible processes at the microscale, especially in environments that are inaccessible with conventional optical frequencies. #ScienceAndTechnology #Microscopy #Physics

A miniature laser source developed by applied physicists at Harvard and TU Wien could pack the power of a laboratory-based spectrometer — an important workhorse tool for precision environmental gas analysis — onto a single microchip. A ring-shaped, “racetrack” quantum cascade laser, the device generates a frequency comb, or a laser that emits many colors of perfectly spaced light. Making these special light sources in the mid-infrared wavelength range is foundational to modern gas-sensing applications. But making bright, stable compact frequency combs is a perennial engineering challenge. Today, they are most often generated by conventional lasers that are sensitive to optical feedback and require bulky stabilizing equipment. The new device from the Harvard team makes inherently stable frequency combs that don’t require any outside moving parts, paving the way for miniaturization. By enabling chip-scale, dual-comb spectrometry, the research could lead to compact sensors for greenhouse gas monitoring, industrial process monitoring, or even medical diagnostics like breath analysis. The research was co-led by Theodore Letsou, a postdoctoral researcher in SEAS Professor Federico Capasso’s group, and Johannes Fuchsberger, a graduate student advised by Professor Benedikt Schwarz at TU Wien. It is published in Optica. Learn more: https://bit.ly/4tfIg4G

When a Optica Student Chapter makes the most of the opportunities available to them. Fabulous work by the Oxford Optics and Photonics Society team arranging a fantastic day of visits and meetings at nearby Harwell, on Friday 27 March. Adrian-Andrei Enoae and the Chapter gathered 14 delegates from the faculties of Engineering, Physics and Chemistry at the University of Oxford, and they had a day packed with action. Welcoming them to the facilities at STFC Harwell site were Danielle C. and Ayman Qureshi, together with their super-talented colleague Helen Towrie, for a day of visits and talks about the new Extreme Photonics Applications Centre (EPAC) facilities, and DiPole, followed by the nearby labs of Artemis and Octopus research groups. Super impressive work is ongoing, not to mention the soon-to-be 20 PW laser at Vulcan. If you are interested in science and don't know what STFC Harwell offers, now is the time to find out more. And the students did the most of this memorable occasion, getting inside views on many of the labs, too. Thank you Mariastefania De Vido, Gary Quinn, Luke McHugh, Matt, Robert, Igor, James and Megan Pritchard for making yourselves available for the lab visits and tours. Really good to see you again too! Add to that a great poster session, with participation of the Target Factory team, now implementing automated systems to satisfy the higher demand that will come from EPAC, nanoscale precision engineering, all done by a very talented young team! This really epitomised what can be done, and it was great to have a really engaged group together with wonderful hosts. Thank you, everyone, for a really enjoyable day!
