The time/frequency unit is the most accurate among the seven basic units, so many measurement studies that pursue ultra-high accuracy and sensitivity will be transformed into frequency measurements to achieve higher measurement accuracy and sensitivity. For example, by measuring the relative changes in the ratio of different atomic transition frequencies, ultralight dark matter can be detected or ...
Coherent Corporation, the leader in erbium-doped fiber amplifier pumped laser technology for deployment in optical networks, announced today the launch of the industry's first pumped laser module in a 10 pin butterfly package with an output power of 1200 mW.The rapid development of optical communication technology is reaching the theoretical limit of fiber capacity and driving the expansion of tr...
Recently, the research team of the State Key Laboratory of High-Field Laser Physics at the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences has made progress in using high-field lasers to drive the even harmonic frequency shift of single-layer MoS2. The results were published in Optics Express under the title "Frequency shift of even-order high harmonic generation...
Lawrence Livermore National Laboratory (LLNL) and the Extreme Light Infrastructure (ELI) European Research Infrastructure Consortium (ERIC) have announced that they have signed a new Memorandum of Understanding. This builds on their existing decade of strategic collaboration to advance high-power laser technology.“We are looking forward to expanding our existing collaborations with ELI on areas su...
Recently, Qing Guangyan, a researcher team from the Research Group on Bioseparation and Interface Molecular Mechanism (1824 Group) of Biotechnology Research Department of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, designed and prepared a highly solid cellulose photonic hydrogel with reconfigurability and mechanical discoloration. This preparation method opens up a new way t...
