Ultra short laser pulses for local welding (Source: Fraunhofer IOF)With the accelerated evolution of electronic devices towards high power, high frequency, and miniaturization, ceramic substrates have become core materials in fields such as power semiconductors, 5G communications, and new energy vehicles due to their excellent thermal conductivity, insulation, and high temperature resistance. H...
Using light beams for communication is not a new idea, even outside of Star Trek, Star Wars, and other similar fantasy stories. Scientist and science fiction writer Arthur Clark predicted that beam communication, at that time modern satellite communication was just a dream.In 1975, the magazine published an article about laser communication or laser communication equipment. The demonstrati...
Recently, a start-up company co founded by Nobel laureate Hideyoshi Nakamura in San Francisco plans to commercialize nuclear fusion reactors using laser technology around 2030.Hideyoshi Nakamura won the 2014 Nobel Prize in Physics for inventing blue light-emitting diodes. He founded Blue Laser Fusion in Palo Alto, California in November 2022. Partners include Hiroaki Ohta, former CEO of drone manu...
Recently, the semiconductor industry has adopted Extreme Ultraviolet Lithography (EUVL) technology. This cutting-edge photolithography technology is used for the continuous miniaturization of semiconductor devices to comply with Moore's Law. Extreme ultraviolet lithography (EUVL) has become a key technology that utilizes shorter wavelengths to achieve nanoscale feature sizes with higher accuracy a...
Image source: Federal Institute of Technology in Lausanne, SwitzerlandScience and Technology Daily, Beijing, September 27th (Reporter Zhang Jiaxin) Commercial femtosecond lasers are manufactured by placing optical components and their mounting bases on a substrate, which requires strict alignment of optical components. So, is it possible to manufacture femtosecond lasers entirely from glas...
