Spectroscopic analysis and persistent photon-gated spectral hole burning in LiF:F2− color center crystal

Vladimir Fedorov, Sergey Mirov, Michael S. Ashenafi +1 more

Luminescence and absorption spectra of LiF crystals with F2− color centers (CCs) were studied in the 14–300 K temperature range. The Huang–Rhys factors measured from absorption and emission spectra were equal in magnitude and calculated to be 3.2 and 2.72 at 77 and 300 K, respectively. It was shown that below 40 K inhomogeneous broadening of the zero phonon line of the F2− CC prevails over homogeneous broadening. Inhomogeneous broadening of the zero phonon line was observed to vary from 5 to 15 cm−1 for different crystal preparations. Persistent spectral hole burning stable at room temperature was realized in LiF:F2− crystals.

X‐Rays in Diamond Photonics: A New Way to Control Charge States of Color Centers

Eduard S. Sektarov, Vadim Sedov, Victor Ralchenko +1 more

This work is focused on the investigation of the X‐ray's interaction with the color centers in diamond. X‐rays have the high penetrating power of radiation, which allows performing unhindered modifications deeply in the bulk of diamond crystals. Herein, it is shown that X‐rays irradiation of diamond can change the charge states of its defects, including silicon‐vacancy (SiV) and nitrogen‐vacancy (NV) color centers. By studying low‐temperature absorption spectra, it is shown that negatively charged SiV− and NV− centers partially transform into neutrally charged SiV0 and NV0 centers, accordingly. In addition, new absorption lines are registered, which may belong to other charge states of color centers. The results open a new way for the study of charge states for defects in various crystals (not limited to diamond), as well as allow the control over the charge state of color centers for diamond‐based quantum optics.

Nonlinear optical phase conjugate effect caused by F 2 - color center in LiF crystals

Tao Zhang, Liangfeng Wan, Ruan Yong-feng

We report the experimental observation of nonlinear optical phase conjugate (NOPC) effect caused by the resonant saturable absorption of F 2 - centers in LiF crystals. The experiment was performed by making use of degenerate four-wave mixing in the laser cavity. We also give the curve of the phase conjugate reflectivity versus the incident energy of the probe light.
