Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...

Exail, the France-headquartered photonics company, says it has won a contract with the French Space Agency (CNES) to develop and deliver an “ultra-stable” laser system for the planned Laser ...

For most of us, the mention of “technological innovation” brings to mind images of the technologies that have become useful for our everyday lives. We imagine aspiring app developers lounging about ...
