Researchers at the University of Illinois at Urbana Champaign have developed compact visible wavelength achromatic mirrors using 3D printing and porous silicon, which are crucial for miniaturization and lightweight optical devices. These high-performance hybrid micro optical devices can achieve high focusing efficiency while minimizing volume and thickness. In addition, these microlenses c...
Recently, scientists from the National Ignition Facility at Lawrence Livermore National Laboratory in California produced a burst of energy by bombarding hydrogen pellets with 192 laser beams, briefly reproducing the fusion process that powers the sun. This is a repeat of an experiment in December last year, but this time the scientists generated more energy, with a gain almost double that of the ...
According to industry forecasts, the medical laser market in India, especially in the field of medical aesthetics, is expected to be worth up to 71572 million rupees in fiscal year 2023. It is expected that this number will increase to 1.8358 billion rupees by fiscal year 2031, with a compound annual growth rate of 12.49%.Alma Medical, a global innovator in the field of medical lasers in Israel, h...
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...
Recently, Professor Chen Qian and Professor Zuo Chao's research group from the School of Electronic Engineering and Optoelectronic Technology at Nanjing University of Science and Technology proposed a minimalist optical imaging method based on programmable masks - programmable Fresnel zone aperture lensless imaging technology. The related achievement, titled "Lensless Imaging with a Programmable F...
