AOSense has served as a prime contractor for numerous government projects and produced commercial devices for large defense contractors, national laboratories, and universities.

Laboratory-based atomic sensors set the standard for precision and accuracy. For example, the best atomic clock has a timing error of less than 1 s over 30 billion years. Such exquisite performance can improve existing technologies such as GPS and inertial navigation as well as enable entirely new applications in coherent imaging, radar, and global intelligence, surveillance, and reconnaissance (ISR). Building an atomic sensor that achieves this performance requires mastering a complex system of lasers and optics, vacuum, electronics, and control hardware. To be practical, these sensors also need to operate for days to years without direct contact.

AOSense sensor solutions trade performance for size and simplicity, resulting in practical atom-optic sensors that can operate in real-world environments. Meeting the aggressive size, weight, and power constraints of our compact designs has required AOSense to engineer many novel custom components including vacuum, laser, and electronics hardware.

Gravimeter sensor and control electronics


AOSense delivered its first commercial compact gravimeter to an aerospace customer in 2010. Gravimeters are specialized accelerometers used to measure local gravity or variations in the gravitational field of the Earth. The AOSense compact gravimeter integrates an entire lab of equipment into a single portable sensor head and controller, incorporating all necessary lasers, vacuum, and electronics to cool, control, and readout the atomic test masses. The sensor is capable of operating autonomously and acquiring data for weeks. The 20 Hz sampling rate is compatible with operation in dynamic environments.

AOSense External Cavity Diode Laser (ECDL)

External Cavity Diode Lasers (ECDLs)

AOSense has developed a line of compact external cavity diode lasers (ECDLs) offering narrow linewidth (<100 kHz) and excellent stability in a small package. Paired with our custom current and temperature controllers, the laser system offers excellent performance in a novel ECDL architecture that is less sensitive to vibration than other designs.

Atom sources

AOSense has developed novel custom atom trapping and vacuum hardware in response to the challenging size, weight, and power specifications of our customers. Our components are engineered to be considerably smaller than standard laboratory hardware, consuming little or no electrical power and requiring no water cooling.
