In the interaction between ultra short and ultra strong lasers and matter, short pulse width and high energy electrons are generated, commonly referred to as "hot electrons". The generation and transport of hot electrons is one of the important fundamental issues in high-energy density physics of lasers. Superhot electrons can excite ultrafast electromagnetic radiation in a wide range of wavelengt...
A sketch of the imaging and holographic parts of a transient holographic microscope, including a pulse sequence, to illustrate the signal modulation method. By imaging the pinhole array at the sample position, a diffraction limited excitation spot array can be created, allowing for the simultaneous collection of transient data around 100 excitation spots.Femtosecond transient microscopy is an impo...
On July 7, the European Space Agency (ESA), established Europe’s first deep-space optical communication link with NASA’s Psyche mission using a high-power fiber laser system supplied by NKT Photonics, a subsidiary of Hamamatsu.NKT’s announcement stated, “This achievement, conducted with NASA/JPL’s Deep Space Optical Communications (DSOC) demonstrator, marks a significant leap forward in high-data-...
Imagine soaring above the Earth, the world unfolds in patterns and reliefs, and the terrain whispers its secrets in the wind. Now imagine capturing these whispers and translating them into a digital language to draw our world map with unprecedented accuracy. Welcome to the forefront of laser scanning drones, a technological ballet in the sky where the fusion of flight and laser precision is reshap...
A team of researchers from Georgia Institute of Technology has developed a scalable printing system for metal nanostructures using a new technology called superluminescent light projection. The inventor of this technology Dr. Sourabh Saha and Jungho Choi submitted a patent application for nanoscale printing.Nowadays, the cost of existing nanoscale printing technologies hinders their widespread use...
