AU Lab

AU Lab. The Advanced Ultrafast Laboratory, commonly known as AU Lab, is a premier research facility dedicated to the development and application of ultrafast laser and particle beam technologies. Established in 2018, it operates as a core facility within the Advanced Ultrafast Technologies Consortium, a partnership of leading academic, government, and industrial entities. The lab's mission focuses on pushing the frontiers of attosecond science, advanced materials processing, and next-generation medical imaging, serving as a critical hub for both fundamental research and industrial innovation.

Overview

Situated in the heart of Silicon Valley, AU Lab is strategically positioned to foster collaboration with major technology firms like Intel and Applied Materials, as well as prestigious academic partners including Stanford University and the University of California, Berkeley. The facility is directed by Dr. Elena Vance, a renowned physicist previously associated with the Max Planck Institute for Quantum Optics. Its research portfolio is intentionally interdisciplinary, bridging gaps between quantum optics, condensed matter physics, and bioengineering. This integrated approach has made the laboratory a key contributor to several high-profile initiatives, such as the DARPA-funded PULSE program and the European Union's Horizon Europe framework.

History

The concept for AU Lab originated from a 2015 white paper co-authored by researchers from the Lawrence Livermore National Laboratory and MIT, which identified a critical need for a user facility dedicated to ultrafast technology translation. Following a successful proposal to the National Science Foundation, construction began in 2017 on a site provided by the California Institute of Technology. The lab was officially inaugurated in 2018 by then-United States Secretary of Energy Rick Perry. A significant early milestone was achieved in 2020 when its team, in collaboration with the SLAC National Accelerator Laboratory, demonstrated the first commercially viable attosecond X-ray source. This success led to a major expansion in 2022, funded in part by a grant from the Gordon and Betty Moore Foundation.

Features and capabilities

The laboratory's core infrastructure is centered around its flagship Ti:sapphire laser system, capable of generating pulses shorter than 100 attoseconds. This system feeds into multiple experimental endstations, including a cryogenic electron microscopy suite for studying quantum materials and a dedicated plasma physics chamber for inertial confinement fusion research. A unique capability is its integrated particle accelerator beamline, which allows for concurrent laser-plasma acceleration and synchrotron radiation experiments. The facility also houses a state-of-the-art cleanroom for nanofabrication and a high-performance computing cluster named after pioneer Donna Strickland, used for real-time computational physics modeling.

Applications

Research at AU Lab has led to transformative applications across multiple sectors. In healthcare, its technologies have advanced proton therapy systems for cancer treatment and enabled novel optical coherence tomography techniques for early disease detection. Within the semiconductor industry, the lab's ultrafast lasers are used for precise circuit editing and the development of extreme ultraviolet lithography sources. Its work in fundamental science has provided new insights into photosynthesis and high-temperature superconductivity. Furthermore, partnerships with agencies like NASA and the National Institute of Standards and Technology have applied its diagnostic tools to problems in aerospace engineering and quantum metrology.

Technical specifications

The primary laser system delivers peak powers exceeding 10 terawatts at a repetition rate of 1 kilohertz, with a central wavelength tunable between 700 and 900 nanometers. The attached free-electron laser produces X-ray pulses with energies up to 10 keV. The main experimental hall is a Class 1000 cleanroom with vibration isolation specifications meeting ISO standard 14644-1. The facility's data acquisition systems can handle throughputs of over 100 gigabytes per second, supported by a petabyte-scale storage archive. Power stability is maintained by a dedicated electrical substation and backup systems from Caterpillar Inc., ensuring uninterrupted operation for long-duration experiments.
