Electronic Structure of N-V Centers and Terahertz Spectroscopy of Diamond
We report an essentially complete characterization of energies and relaxation processes of the lowest seven electronic states of the N-V (nitrogen-vacancy) center in diamond using several different nonlinear l...

Photoluminescence of Silicon Nanostructures Formed by Ion Beam Implantation
A new method was used to fabricate nanometer-scale structures in Si for photoluminescence (PL) studies. He ions were implanted to form a dense subsurface layer of small cavities (1–8 nm diameters). The implant...

CW Four-Wave Mixing in Synthetic Diamond
We report efficient CW optical phase conjugation and resonantly enhanced four-wave mixing spectroscopy of the N-V color center in synthetic diamond. An ultra-narrow resonance is observed in the room temperatur...
