A robust, field-deployable, low-cost mode-locked laser oscillator for deployed optical atomic clocks
Abstract: Frequency combs have been investigated in the laboratory over the course of the last 25 years in awide range of implementations and applications including but not limited to optical atomic clocks, precisionmetrology, precision spectroscopy, LIDAR, and low-phase-noise RF generation. While the Nobel prizewinning technology of frequency combs have shown their usefulness in a variety of applications, there havebeen few demonstrations of this technology in real-world applications. Here we present a mode-lockedoscillator that has been designed to be environmentally robust and low cost, while maintaining suitabilityfor use in frequency comb applications. Vescent Photonics has designed environmentally robust oscillatorsand frequency combs for government programs including satellites and terrestrial moving platforms. Thesedesigns allow for repetition rate matching at the time of manufacture, which is an important considerationfor integration of this technology into several key applications. Vescent Photonics will report on theperformance, environmental robustness, and cost of these fiber laser systems.
