Eagleyard Lasers Used on ESA Gaia Star Surveyor

Facebook Twitter LinkedIn Email Comments
Two laser diodes from Eagleyard Photonics GmbH are being used on board the European Space Agency’s Gaia star surveyor.

The single frequency DFB-852 laser diodes in a 14-pin butterfly housing are responsible for keeping the two telescopes in the right position, helping achieve Gaia’s mission to create the most accurate 3D map of the Milky Way. They were shipped in 2010, with Gaia beginning its work in July of 2014.

On its way to assembling the most detailed 3D map ever made of the Milky Way, Gaia has pinned down the precise position and brightness of more than 1 billion stars. It also features the distances and motions across the sky for more than 2 million stars.

Eagleyard is a developer of high-power laser diodes based on gallium arsenide.
