Project Description

Multi-Channel Tunable Source for Atomic Sensors
This Phase II SBIR will seek to develop a prototype laser source suitable for atomic interferometry from compact, robust, integrated components. AdvR's design is enabled by capitalizing on robust, well-commercialized, low-noise telecom components with high reliability and declining costs which will help to drive the widespread deployment of this system. The key innovation is the combination of current telecom-based fiber laser and modulator technology with periodically-poled waveguide technology to produce tunable laser light at rubidium D1 and D2 wavelengths (and expandable to other alkalis) using second harmonic generation (SHG). With this technology, multiple channels can be independently tuned to produce the fields needed for addressing atomic states in atom interferometers and clocks. In addition, this technology could be useful in the development cold-atom inertial sensors and gyroscopes. More »
