Hackaday will launch cool projects that may stimulate others to expand and enhance it, and even move in a completely new direction. This is the way the most advanced technology continues to evolve. This DIY spectrometer project is a great example of this spirit. It comes from Michael Prathofer, who was inspired by Les Wright's PySpectrometer, a simple device pieced together by a pocket spectrom...
In the interaction between ultra short and ultra strong laser and matter, electrons with short pulse width and high energy 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 a wide range of ultrafast electromagnetic radiation, as well...
Although lasers are common in daily life, their applications go far beyond the scope of light shows and barcode reading. They play a crucial role in telecommunications, computer science, and research in biology, chemistry, and physics. In the latter field, lasers that can emit extremely short pulses are particularly useful, approximately one trillionth of a second or less.By operating these lasers...
Trotec Laser, a manufacturer of laser technology in Upper Austria, is opening a new laser cutting competence center. The expanded showroom in Darmstadt now also houses three new large format laser cutters from the SP series. This strategic move is designed to meet the growing demand for large format laser cutting solutions.To celebrate the reopening of the Darmstadt Competence Centre, Trotec will ...
Recently, Yang Shanglu, a researcher at the Laser Intelligent Manufacturing Technology Research and Development Center of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made new progress in laser welding of the fourth-generation reactor-molten salt reactor structural material Ni-28W-6Cr nickel-based superalloy.The research team applied the high power fiber ...
