Short wave ultraviolet all solid-state coherent light sources have the characteristics of strong photon energy, practicality and precision, and high spectral resolution. They have significant application value in laser precision processing, information communication, cutting-edge science, and aerospace fields.The core component of obtaining all solid-state shortwave ultraviolet lasers is nonlinear...
Alpes Laser was founded in 1998 in Nazhatel, Switzerland and was the first company to bring quantum cascade lasers to the market. It released its first continuous laser in 2001 and its first high gain laser in 2009, thus maintaining this priority position.In 2004, the first commercial laser was introduced.Principle: In a single mode laser, the grating is etched into the active region to force the ...
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...
Researchers from the Welding Research Institute of Aachen University of Technology in Germany reported on the development of a stable welding process for electron beam welding of thick plates used in the construction of offshore wind turbines. The relevant research results were published in Materials Science and Engineering Technology under the title "Development of a robust welding process for el...
Scientists are exploring new ways to get around limitations on the lithography machines used to produce microchips. Researchers are using particle accelerators to create new laser sources that could lay the foundation for the future of semiconductor manufacturing.Plans are underway to build a particle accelerator with a circumference between 100 and 150 meters (328 and 492 feet), about the size of...
