Research backgroundIn transportation, industrial production, and practical life, icing often brings great troubles, and the most serious is that during the flight of an aircraft, key components once frozen will seriously affect navigation safety.The traditional passive deicing and anti icing strategies for aircraft, such as mechanical vibration and anti freezing liquids, have problems such as inco...
When scientists discovered that laser pulses can rapidly cause refractive index changes in the medium, resulting in "photonic time crystals (PTC)" in the near-visible light band, the door to a disruptive new application in optics seemed to quietly open.Scientists have a certain degree of understanding of photonic crystals and time crystals, the two have almost nothing in common, the basic common p...
On March 28th, Marvel Fusion, a laser fusion company from Munich, Germany, announced the completion of a B+round financing of 50 million euros, bringing the total amount of this round of financing to 113 million euros. It is reported that the company's cumulative financing has reached 385 million euros, making it the largest fusion company in Europe in terms of financing scale. This capital incr...
The N-linear optical microscope has completely changed our ability to observe and understand complex biological processes. However, light can also harm organisms. However, little is known about the mechanisms behind the irreversible disturbances of strong light on cellular processes.To address this gap, the research teams of Hanieh Fattahi and Daniel Wehner from the Max Planck Institute for Photos...
Researchers from Chalms University of Technology in Sweden have successfully improved the efficiency of optical microcombiners, making them a high-performance laser. This breakthrough will have a wide impact in fields such as space science and healthcare.The two rings in the figure are micro resonators, which play a crucial role in the implementation of efficient micro combs.The importance of micr...
