OIDA Sponsored Webinar: Optical Frequency Combs and Their Role in Modern Laser Cooling and Trapping Systems

16 July 2020, 13:00 - 14:00 - Eastern Daylight Time (UTC - 04:00)

Quantum technologies are currently experiencing a surge in activity. This webinar will focus on laser cooling and trapping which has recently seen a shift from purely fundamental research toward a focus on increased application-driven effort such as quantum computing, quantum sensing, quantum communication, and quantum metrology. The scientific community faces a new set of challenges and it is essential for industry to continue to provide the tools necessary to enable and accelerate research and application development. Frequency combs are an essential component in optical clocks, but possess often overlooked properties which make them ideal in a broad range or cooling and trapping systems. In addition to being the ultimate laser reference, combs can provide a convenient backbone for entire laser systems, streamlining an optical lab. We will cover the relevant frequency comb properties, locking schemes, and integrated components which are moving lasers off the optical table and into convenient, clean packages without compromising performance. The technological frontier in computation, communication, and medicine is increasingly utilizing the power of quantum physics. Quantum processes are performed by interacting with microscopic systems such as atomic ions, neutral atoms, resonators, and photons to execute operations and store information. Atomic ions make an exceptional platform for many of the most important applications in quantum information. Trapped ion systems require excellent vacuum cells for keeping an ion trapped for long periods of time, and robust laser systems for writing and storing information. ColdQuanta has developed a compact ion trap package that is a fraction of the size of the state-of-the-art vacuum systems seen in laboratories around the world. We will review a compact ion trapping system that we have built in collaboration with TOPTICA and other partners, including Optosigma, Coherent, Duke University, and Sandia National Labs.
