Anatomical MRI with an atomic magnetometer
I. Savukov, T. Karaulanov
Ultra-low field (ULF) MRI is a promising method for inexpensive medical imaging with various additional advantages over conventional instruments such as low weight, low power, port…
Polarized alkali vapor with minute-long transverse spin-relaxation time
Misha Balabas, Todor Karaulanov, Micah Ledbetter +1
We demonstrate lifetimes of atomic populations and coherences in excess of 60 seconds in alkali vapor cells with inner walls coated with an alkene material. This represents two ord…
Rubidium dimers in paraffin-coated cells
V. M. Acosta, A. Jarmola, D. Windes +7
Measurements were made to determine the density of rubidium dimer vapor in paraffin-coated cells. The number density of dimers and atoms in similar paraffin-coated and uncoated cel…
Investigation of Anti-Relaxation Coatings for Alkali-Metal Vapor Cells Using Surface Science Techniques
S. J. Seltzer, D. J. Michalak, M. H. Donaldson +17
Many technologies based on cells containing alkali-metal atomic vapor benefit from the use of anti-relaxation surface coatings in order to preserve atomic spin polarization. In par…
Controlling atomic vapor density in paraffin-coated cells using light-induced atomic desorption
T. Karaulanov, M. T. Graf, D. English +10
Atomic-vapor density change due to light induced atomic desorption (LIAD) is studied in paraffin-coated rubidium, cesium, sodium and potassium cells. In the present experiment, low…
Efficient collinear third-harmonic generation in a single two-dimensional nonlinear photonic crystal
Todor Karaulanov, Solomon M. Saltiel
We propose novel multi-phase-matched process that starts with generation of a pair of symmetric second-harmonic waves. Each of them interacts again with the fundamental wave to pro…
