Quarto Application Note
Nathan Lemke and his students at the Bethel University AMO lab locked a laser to a two-photon transition of 85Rb. They used the qNimble Quarto as a modulation source, lock-in amplifier, and PI loop filter servo.
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
Vescent is a developer and manufacturer of novel electro-optic and precision laser technologies. We offer frequency-stabilized narrow linewidth 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 laser design and manufacuring technical challenges. We are adding to our SLICE line of laser control electronics that includes the unique SLICE-QTC four-channel temperature controller for lasers and electro-optics and the SLICE-DHV high-bandwidth PZT controller and 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 optical frequency ƒopt to visible and near infrared (NIR) wavelength comb teeth from 650 to 1600 nm and beyond. Through non-linear frequency conversion techniques, we have generated lockable comb teeth down to 650 nm.
