This Week in Photonics: 3D Holograms Poised to Enter Mobile Devices; TRUMPF/Fraunhofer Enter Agreement (1/20/2022)

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.

Cascade Optical Corporation
Cascade Optical Corporation is a manufacturer of custom thin-film coatings with more than 40 years specializing in ion-assisted deposition, low-temperature, low-stress coatings. Our vast research and design experience, plus innovative techniques, will work for a wide diversification in the electro-optic communities.

Bristol Instruments Inc.
Bristol's popular 871 system measures laser wavelength at a sustained rate of 1 kHz, the fastest available. It also measures wavelength to an accuracy as high as ±0.0001 nm. By combining proven Fizeau etalon technology with automatic calibration, the most reliable accuracy is ensured for the most meaningful experimental results.

ECM USA Inc.
CYBERSTAR Czochralski pullers produce highly uniform, top quality crystals (research size to 100 kg with atmospheres from 0–100 bar vacuum) while being fully computerized for maximum yield & minimal supervision. Our patented automatic diameter control software assists in various crystal growth.
