The proton is a fundamental constituent of the matter. However, it has a complicated internal structure which is difficult to be fully understood. The internal structure of the proton is described by the electronic and magnetic form factors. The charge radius of the proton is defined by these form factors and has been determined experimentally. In recent years, a significant discrepancy between independent measurements of the proton charge radius was reported. This conflict is known as "proton radius puzzle". Even though various interpretations have been proposed, no definitive solution to the problem has been found yet. In order to shed some light on the puzzle, we proposed a new experiment to determine the proton Zemach radius which is defined as a convolution of the charge distribution with the magnetic moment distribution. The proton Zemach radius can be derived from the hyperfine splitting (HFS) in the muonic hydrogen atom. We aim to perform a laser spectroscopy of the muonic hydrogen HFS with the relative uncertainty of 1 ppm and obtain the proton Zemach radius with 1% precision.

“…Moreover, laser wavelengths around 2.9 µm are also suitable pump sources for infrared optical parametric oscillation (OPO) or optical parametric generation (OPG) [43]. One possibility of generating 2.9 µm radiation is the 5 I 6 → 5 I 7 transition of Ho 3+ , which possesses rich energy levels [44].…”

Rare-Earth Tantalates and Niobates Single Crystals: Promising Scintillators and Laser Materials

et al. 2018

Rare-earth tantalates, with high density and monoclinic structure, and niobates with monoclinic structure have been paid great attention as potential optical materials. In the last decade, we focused on the crystal growth technology of rare-earth tantalates and niobates and studied their luminescence and physical properties. A series of rare-earth tantalates and niobates crystals have been grown by the Czochralski method successfully. In this work, we summarize the research results on the crystal growth, scintillation, and laser properties of them, including the absorption and emission spectra, spectral parameters, energy levels structure, and so on. Most of the tantalates and niobates exhibit excellent luminescent properties, rich physical properties, and good chemical stability, indicating that they are potential outstanding scintillators and laser materials.

“…For them phase matching can be achieved, which enables their use in continuously tunable laser sources over wide infrared spectral ranges. [29][30][31][32] Detailed spectroscopic SHG studies of semiconductors at low temperatures, with high spectral resolution, and in applied magnetic field were initiated only in recent years. It was discovered that the application of a magnetic field to the noncentrosymmetric diamagnetic semiconductors GaAs and CdTe, for which SHG is allowed in ED approximation, induces new optical nonlinearities.…”

Optical second harmonic generation in the centrosymmetric magnetic semiconductors EuTe and EuSe

et al. 2010

View full text Add to dashboard Cite

The magnetic europium chalcogenide semiconductors EuTe and EuSe are investigated by the spectroscopy of second harmonic generation ͑SHG͒ in the vicinity of the optical band gap formed by transitions involving the 4f and 5d electronic orbitals of the magnetic Eu 2+ ions. In these materials with centrosymmetric crystal lattice the electric-dipole SHG process is symmetry forbidden so that no signal is observed in zero magnetic field. Signal appears, however, in applied magnetic field with the SHG intensity being proportional to the square of magnetization. The magnetic field and temperature dependencies of the induced SHG allow us to introduce a type of nonlinear optical susceptibility determined by the magnetic-dipole contribution in combination with a spontaneous or induced magnetization. The experimental results can be described qualitatively by a phenomenological model based on a symmetry analysis and are in good quantitative agreement with microscopic model calculations accounting for details of the electronic energy and spin structure.
