Saturable absorption in NV-doped diamond studied by femtosecond Z-scan
Wojciech Talik, Mariusz Mrózek, Adam M. Wojciechowski +1
We investigate nonlinear optical absorption in diamond crystals containing high densities of nitrogen vacancy (NV) centers using open-aperture Z-scan measurements with 230 fs laser…
Low-field all-optical detection of superconductivity using NV nanodiamonds
Omkar Dhungel, Saravanan Sengottuvel, Mariusz Mrozek +5
Nitrogen-vacancy centers in nanodiamond offer a microwave-free, noninvasive platform for probing superconductors via near zero-field cross-relaxation magnetometry. We demonstrate t…
Spin-lattice relaxation of NV centers in nanodiamonds adsorbed on conducting and non-conducting surfaces
