June 2021: Visiting Scholar Samuel Huber returns to University of Wurzburg

During his stay, Samuel worked on several aspects of the E8 apparatus - from constructing lasers for optical pumping to setting up wavelength and light spectrum analyzers. His largest contribution was this locking of the MSquared Ti:Saph laser to a ULE cavity using only a Red Pitaya FPGA device and the PyRPL software package. This gave us an absolute frequency reference for our titanium cooling laser, an essential part in our effort to laser cool titanium.
