Raicol Crystals is entering the world of quantum computing with a new collaboration with Qubitekk of CA, USA, and with funding of The BIRD Foundation.

Quantum-based quantum communication will allow a great deal of information to move quickly, qualitatively, securely and without the influence of distance or environmental conditions. Israeli-American collaboration between the companies will combine the photon-splitting capabilities of crystals of Raicol Crystals and Qubitekk’s quantum entanglement source to replace quantum keys with the aim of developing an elaborate endpoint for the transfer of split photons. This development will enable ultra-fast data encryption and may be used in a variety of areas including financial, security, medical, and governmental systems.

Appeared in several Israeli magazines in May 2020.

A Satellite Lets Scientists See Antarctica’s Melting Like Never Before

Raicol’s RTP Phase Modulator to enhance single-scan acquisition in I-SHG microscopy.

At the link below, you may find an article by a group of researchers of INRS-EMT, Canada.
This article demonstrates, for the first time, the possibility of single-scan acquisition in I-SHG microscopy (1S-ISHG) based on an electro-optic phase-scanner using Raicol’s RTP Phase Modulator using the system described above.
The scan of phase-shifts is performed for each pixel of the I-SHG image being acquired, which corresponds to a total acquisition of only a few seconds, which is speed increase by 20 times from the current pixel scans.
This opens the possibility of measuring – in a minimally invasive way – the relative polarity in many biophysical systems undergoing fast dynamics, e.g. in microtubules in various stages of the mitosis, living bio-samples, or tissues submitted to dynamic traction assays, with an enhanced time resolution.
This technology can also be applied to other SHG enhancements such as polarization-resolved SHG (p-SHG), resulting in similar speed improvement.

ESA-JAXA BepiColombo mission to Mercury (November,29,2018)

We are pleased to announce that at 01:56:28 GMT on October 20, the ESA-JAXA BepiColombo mission to Mercury blasted off on an Ariane 5 from Europe’s Spaceport in Kourou, French Guiana in South America. Ariane 5 carries on board the BepiColombo Laser Altimeter (BELA) in which Raicol ‘s crystals have been used to build a space-qualified Q-Switch for the laser range finder. After a 6-year cruise, the BepiColombo Laser Altimeter will start recording topographic data from orbital altitudes between 400 and 1500 km above Mercury’s surface. This is a joint mission between Europe and Japan. Many actors were involved in the design, construction, and launch of the satellite. Hensoldt Optronics was prime-contractor for the “BELA Laser” for which the Q-Switch was selected.
