Enhanced activation yield of nitrogen-vacancy and silicon-vacancy diamond color centers by proton and carbon irradiation
We investigate the activation yield and optical properties of the negatively charged nitrogen-vacancy (NV −) and silicon-vacancy (SiV −) centers in single-crystal diamonds, focusing on the effect of proton (p) and carbon-ion (C) irradiation on their formation.
Quantum and interband cascade lasers between classical and quantum operation regime
Our work investigates the generation of non-classical light by cascade lasers in the mid-infrared (MIR, 3–5μm) spectral region. Using a MIR-balanced detector sensitive to the intensity noise below the classical level, we demonstrated shot-noise-limited operations of MIR cascade lasers.

Short-term stability of a microcell optical reference based on the Rb atom two-photon transition at 778 nm
We report on the development and short-term stability characterization of an optical frequency reference based on the spectroscopy of the rubidium two-photon transition at 778 nm in a microfabricated vapor cell. When compared against a 778 nm reference signal extracted from a frequency-doubled cavity-stabilized telecom laser, the short-term stability of the microcell frequency standard is until 200 s, in good agreement with a phase noise level of at 1 Hz offset frequency.
