Recently, the IFA2023 Consumer Electronics Show in Berlin, Germany opened, Hisense exhibited "three-color laser projection family bucket" attracted the attention of media and tourists from all over the world.Since Hisense's young fashion brand Vidda launched a series of three-color laser projection, its accumulation based on three-color laser technology is competing globally and has become a...
The pump source, gain material, and resonant cavity are the three elements that make up a laser. Due to the selective effect of the resonant cavity on the lasing frequency, multi longitudinal mode operation is one of the characteristics of fiber lasers based on traditional resonant cavity structures, manifested as periodic beat peaks in the radio frequency (RF) spectrum and periodic fluctuations i...
The ATLAS R&D center is expected to be completed by mid-2026!A powerful new laser research facility located on the Foothills campus of Colorado State University will begin construction this month. The facility is planned to be put into use in mid-2026 and is the result of 40 years of laser development research at Colorado State University. It is a collaboration with the Fusion Energy Science P...
On quartz sheets, the angular rhombic boron nitride crystals with a thickness of only 1 to 3 microns are as thin as cicada wings, but their energy efficiency is 100 to 10000 times higher than traditional optical crystals. At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference held on April 25th, the world's thinnest known optical crystal was listed as one of the top ten technolog...
Recently, the research team of the High end Optoelectronic Equipment Department at the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the study of wavefront calibration methods for interferometer testing. The relevant research results were published in Optics Express under the title of "High precision wavefront correction method ininterometer tes...
