Recently, IPG Photonics, a high-performance fiber laser supplier in the United States, released its first quarter financial report as of March 31, 2024.The financial report shows that IPG Photonics revenue in the first quarter was 252 million US dollars, a year-on-year decrease of 27%; The net profit was 19 million US dollars, a year-on-year decrease of 75%. The change in foreign exchange rate res...
The new device is a frequency comb - a special type of laser that can generate multiple wavelengths of light, each with a fixed frequency interval. On the spectrogram, it looks a bit like the teeth of a comb. In approximately a quarter century since their first development, these "cursor rulers" have completely transformed various high-precision measurements from timing to molecular detection. In ...
Scientists from the Institute of Automation and Control Process at the Far East Branch of the Russian Academy of Sciences described the changes on the surface of monocrystalline silicon during laser processing. The author of this study placed the crystal in a methanol solution and applied a laser pulse lasting one thousandth of a second to the sample, with a pulse count ranging from five to fifty ...
Recently, researchers from Kaunas University of Technology (KTU) in Lithuania and the Tsukuba National Institute of Materials Science in Ibaraki, Japan, have collaborated to successfully develop a new type of nanolaser based on silver nanocubes.Although its structure is small and can only be observed through high-power microscopes, its potential application prospects are broad, and the research te...
