Long Term Ultrastable Laser System at 780 nm for Atomic Clocks

Gener8 and AOSense team together to propose a novel new architecture for a low-phase noise, single-frequency electronically tunable laser at 780 nm. This laser concept has a demonstrated electronic tuning coefficient 2.37 GHz/Volt and will meet all the demanding requirements for atomic clock applications. The compact laser technology is based on previously developed hybrid integration technology that enables the direct optical coupling of active and passive waveguide chips. The integrated design proposed reduces system complexity, lowers cost and lends itself readily to array scaling. A rugged packaging solution is proposed to package the laser head in a volume of 3.0 cubic cm.
