Laser Signal Transmission Bypasses Atmospheric Distortion
Researchers from the International Centre for Radio Astronomy Research (ICRAR) and the University of Western Australia (UWA) claimed a world record for what the team is calling the most stable transmission of a laser signal through the atmosphere. The work stems from a collaboration between the scientists from UWA and ICRAR with researchers at the French National Centre for Space Studies and the French metrology lab Systèmes de Référence Temps-Espace at Paris Observatory.

Laser-Based Method Enables 3D-Printed Glass with Intricate Detail
A laser-powered polymerization process for 3D-printing applications overcomes the need to build a 3D-printed object one layer at a time. A research team from France’s Fresnel Institute and École Centrale de Marseille introduced the method, using it to create miniature models of a bicycle and even the Eiffel Tower from silica glass.

Extreme UV Created from White Light
A method of modifying the spectral width of extreme ultraviolet light (EUV) has been developed by researchers at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy. The scientists used a novel phase-matching scheme in four-wave mixing, which allowed them to compress the spectral width of the initial broadband light by more than a hundred times.

Fourier Transform Infrared (FTIR) Spectrometer: Theory, Practice, and Applications
Wed, Feb 10, 2021 1:00 PM - 2:00 PM EST
This webinar with John D. Gilmore and Slawomir Piatek, Ph.D., of Hamamatsu will review the basic theory behind a Michaelson-Morley interferometer, and will apply it directly to today’s modern MEMS-based FTIR engines. The presenters will compare traditional grating-based spectrometers with FTIR, and the associated technological limitations, such spectral coverage, signal to noise ratio and noise induced by mechanical vibration. Participants will witness a live MEMS FTIR product demonstration and will learn about FTIR applications and some market challenges and solutions. Presented by Hamamatsu Corporation.

.: All Things Photonics

Jess Wade from Imperial College London’s Blackett Laboratory kicks off Season 3 of All Things Photonics with expert insights on OLEDs, chiral materials, and the not-so-clear-cut relationship between science and equity. Through the lens of SPIE’s very first Diversity Outreach Award winner, listeners will enjoy a candid conversation on topics ranging from polymer conjugation to breaking biases in STEM and beyond.
