Working in close contact with our customers to develop cutting-edge systems for high-resolutions laser spectroscopy.
In one of our experiments, we were interested in single-photon excitation of the atoms in a degenerate Fermi gas of lithium atoms to a Rydberg state. We needed a laser at the UV wavelength of 230 nm. LEOS was able to provide us with a competitive turn-key system that delivered about 70 mW of UV through two stages of second harmonic generation starting with infrared light from an amplified diode laser system. The system was shipped in parts and a first year-graduate student was able to get it up and running

The UV light from the LEOSolutions laser system was used to excite atoms from a single-spin species band insulator of lithium atoms in an optical lattice to a Rydberg state with a blockade radius comparable to the lattice spacing. This realizes a transverse field quantum Ising model with an antiferromagnetic ground state, where the Rydberg atoms exhibit checkerboard correlations. The Rydberg atoms were photoi
