Congratulations to Shankar Menon of the University of Chicago. Shankar has won a free qNimble Quarto data acquisition module and experimental control center! Shankar, who is a graduate student in the labs of Hannes Bernien at the Pritzker School of Molecular Engineering, says, "I am very excited to win the raffle and even more excited to see and work with the qNimble Quarto." We look forward to hearing about how Shankar uses this versatile device.
The Quarto features low latency and jitter with a sampling rate of 1 MS/s and four high-resolution (16 bit) A2D channels and 8 bits of digital I/O. It can be programmed via the ArduinoTM IDE to act as a loop filter, lock-in amplifier, or other DSP modalities.

Vescent awarded $1.25M Direct-to-Phase II SBIR

Vescent has been awarded a $1.25M Small Business Innovation Research (SBIR) grant from the Air Force (AFRL, WPAFB) to develop a fully stabilized, multi-gigahertz-repetition rate optical frequency comb (OFC). 



Vescent has been awarded a $250k PH I SBIR to commence the development of a stand-alone, multi-axis, compact portable quantum accelerometer.  By enabling inertial navigation systems, this accelerometer will help mitigate the threat to GPS-based positioning which can be easily jammed or spoofed.  This threat extends to the real possibility of complete incapacitation or even destruction of the satellites upon which GPS depends by a hostile actor.  Even in peacetime, GPS signals are not available underground and undersea.  

To date the size, weight, and power of prototype quantum accelerometrs, along with their fragility preclude true field usage of this technology.  The so-called MAGIS program (Multi-axis Atom-interferometer Grating-chip Inertial Sensors) will culminate at PH III in real, field-deployble hardware. The MAGIS approach is based on a light-pulse atom interferometer activated by second genration compact, environmentally robust, frequency agile laser systems designed and built by Vescent.  

This program will be executed in collaboration with Sandia National Labs.  SNL will provide the physics package.


Vescent develops and manufactures novel electro-optic and laser technologies.  We offer frequency-stabilized diode laser systems, precision control electronics, accessory electro-optic modules, and now mode-locked lasers and frequency combs.

Our scientists and engineers are continuously developing cutting-edge solutions to technical challenges.  We are adding to our SLICE line of control electronics that includes the unique SLICE-QTC four-channel temperature controller and the SLICE-DHV high-bandwidth high-voltage amplifier.

The family of Vescent frequency comb products is growing.  The turnkey FFC-100 and Modular FFC-CM series is now joined by the capability to lock ƒopt to visible and NIR wavelength comb teeth.  Through frequency conversion techniques, we have generated lockable comb teeth down to 650 nm.
