Abstract

Observation of the resonance enhancement of the intensity of light scattering by optical phonons in a diamond crystal with nitogen-vacancy centres is reported. It is established that the unusual resonance with electronic transitions for optically active nitrogen impurities with both zero-phonon-lines plays the determining role in the increase in intensity of such scattering: at 575.468 nm for a neutral NV⁰ center and at 637.874 nm for a negatively charged NV^– center. The obtained experimental data indicate the detection of a strong resonant-intensity amplification in the input scattering channel for the NV⁰ center and in the output channel for the NV^– center.

具有氮空位中心的金刚石晶体中光子的共振光散射。

摘要

据报道，在具有氮化物-空位中心的金刚石晶体中，通过光学声子共振散射增强了光子的散射强度。可以确定的是，带有零声子线的旋光氮杂质的电子跃迁的不寻常共振在这种散射强度的增加中起着决定性的作用：对于中性NV ⁰中心在575.468 nm处，对于中性NV ⁰中心在637.874 nm处。带负电的NV ^–中心。获得的实验数据表明在NV ⁰中心的输入散射通道和NV ^–中心的输出通道中检测到强共振强度放大。
