Mirror Specifications and Energy-Efficient Design Support Increasingly Portable System for Laser Precision at Room Temperature
A team of MIT physicists, working with researchers from Louisiana State University (LSU) and Crystalline Mirror Solutions (CMS, now part of Thorlabs Inc.) has designed a quantum “light squeezer” capable of limiting quantum noise in laser beams. The system retains the full range of quantum mechanical properties at room temperature.

Tunable Laser Determines Best UV Wavelengths for Germ Eradication
While awaiting full access to their labs due to COVID-19 restrictions, scientists at the National Institute of Standards and Technology (NIST) have taken the time to report on research conducted in 2012 on the disinfection of drinking water using ultraviolet (UV) light. The research was published online in July 2020 by the Review of Scientific Instruments.

HyperFine Brillouin Spectrometer

LightMachinery Inc.
The great challenge with Brillouin spectroscopy is that the scattered signal from the un-shifted wavelength of the laser can overwhelm the small Brillouin shifted return signal. LightMachinery has combined its leading-edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shifted laser frequency.
