German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
Recently, Hu Lili, a research team of the High Power Laser Unit Technology Laboratory of the Chinese Academy of Sciences Shanghai Institute of Optics and Fine Mechanics, used a method combining experiment, molecular dynamics simulation and quantitative structure property relationship analysis (QSPR) to study aluminum phosphate glass, and the related research results were published in the Journal o...
Recently, the Laser Energy Laboratory (LLE) at the University of Rochester installed a new supercomputer to support its laser fusion experiments.The new supercomputer has increased the computing power of the laboratory by four times and shortened the time required to complete certain projects from 30 weeks to a few days.The Laser Energy Laboratory (LLE) at the University of Rochester is one of the...
Short wave ultraviolet all solid-state coherent light sources have the characteristics of strong photon energy, practicality and precision, and high spectral resolution. They have significant application value in laser precision processing, information communication, cutting-edge science, and aerospace fields.The core component of obtaining all solid-state shortwave ultraviolet lasers is nonlinear...
Additive manufacturing, also known as 3D printing, has completely changed many industries with its speed, flexibility, and unparalleled design freedom. However, previous attempts to manufacture high-quality optical components using additive manufacturing methods often encountered a series of obstacles. Now, researchers from the National Research Council of Canada have turned to fuzzy tomography (a...
