Welcome to Vescent Photonics
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.
Vescent is pleased to announce the FFC-100 - our first turn-key Frequency Comb product!
We are proud to introduce the FFC-100 Fiber-based Frequency Comb. The FFC-100 offers a full octave of wavelength coverage with tight locks on ƒopt and ƒCEO that support the requirements of the next generation of optical atomic clocks. The complete FFC-100 fits into a single 2U 19″ rack mount chassis for a compact, economical comb solution.
Visit the FFC-100 web page for more details. With ADevs of <10-19 for ƒCEO and <10-20 s for ƒopt at 104 s, the FFC is ready for time transfer experiments or optically referenced microwave generation. Our unique ability to match the repetition rates of multiple combs to within a fraction of the dynamic range of their control inputs enables various dual comb spectroscopy experiments. Locking to an optical frequency reference allows the FFC-100 to act as a precise "frequency ruler" for cold atom and quantum sensing applications.

New Publication with Menhir Lasers
D. Fang et al. from the Karlsruhe Institute of Technology and elsewhere recently publsihed a paper detailing a 320 GHz Optical Analog-to-Digital Converter based on the Menhir-1550 laser. Read all about it here.
The Nobel Prize in Physics 2021 was awarded "for groundbreaking contributions to our understanding of complex systems" with one half jointly to Syukuro Manabe and Klaus Hasselmann "for the physical modelling of Earth's climate, quantifying variability and reliably predicting global warming" and the other half to Giorgio Parisi "for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales."

IonQ becomes the first publicly traded, pure-play Quantum Computing Company and celebrates by ringing in the opening of the New York Stock Exchange. See it happen!
Congratulations to the whole IonQ team.
New Application Note: Locking CW Lasers to a Frequency Comb Tooth
A typical applcation for frequency combs is to use its teeth as a "frequency ruler." This is done by offset locking a "slave" laser to a comb tooth of precisely known frequency. In this application note, we lock a Rio Planex narrow-linewidth cw laser to an FFC-100 Frequency Comb tooth and measure the salient properties of the system. View and download application note.

Wenjun Zhou from the Department of Biomedical Engineering, University of California at Davis and his colleagues at UC Davis and NYU Langone have used our D2-100-DBR 852 nm single frequency laser in a technique they call Functional Interferometric Diffusing Wave Spectroscopy to non-invasively and economically monitor blood flow in the human brain.
