Frequency stabilization of a diode laser on the 5P → 5D transition of the Rb atom
Laser Physics. 2017. Vol. 27. No. 5. P. 055703.
In this work, we investigated the frequency stabilization method of a diode laser that operates on the excited state transition 5P→5D of Rb atoms. The described technique allows simple control of the diode laser frequency stabilization to be performed. The critial parameters of stabilization, such as laser intensity and the temperature of a reference cell, have been investigated and long-time laser stability has been demonstrated with frequency stability of about 1 MHz.

To date, the design of stable panchromatic metal complexes simultaneously exhibiting reversible redox behavior remains a challenging endeavor, underscoring the need for new ligand platforms to expand their absorption spectrum. In this study, we report the synthesis and characterization of octahedral bis-cyclometalated iridium(III) complexes with redox-active o-semiquinone/o-iminosemiquinone ancillary ligands, which exhibit exceptional chemical stability and intense ...

Optimal conditions have been selected for the production of new phenol—azo dyes of different compositions, namely 2-phenyldiazenyl-4-(2-phenylpropan-2-yl)phenol and (2,6-dibromo)phenyldiazenyl-4-(2-phenylpropan-2-yl)phenol. The synthesized dyes were used for nucleophilic substitution with 3- and 4-nitrophthalonitrile to form 3/4-[2-phenyldiazenyl-4-(2-phenyl)propan-2-yl]phenoxy- and 3/4-[2-(2,6-dibromo)phenyldiazenyl]-4-(2-phenylpropan-2-yl)phenoxypthalonitriles. The metal complexes were synthesized by template condensation in a solution of the corresponding phthalonitrile with zinc or magnesium ...

Peripheral phenyl-substituted metal phthalocyanines with thio and oxa substitution in the spacer bridge fragment were obtained in the work. Spectroscopic properties were studied for the obtained complexes, and the main patterns of behavior and characteristics change depending on the solvent and the nature of the spacer atom. It is shown that the replacement of an oxygen ...

Tin-Vacancy (Sn-V) colour centres in diamond have a spin coherence time in the millisecond range at temperatures of 2 K, so they are promising to be used in diamond-based quantum optical devices. However, the incorporation of large Sn atoms into a dense diamond lattice is a non-trivial problem. The objective of our work is to use ...

We report the first measurement of the inclusive e+e−→bb¯→D±sX and e+e−→bb¯→D0/D¯0X cross sections in the energy range from 10.63 to 11.02. Based on these results, we determine σ(e+e−→B0sB¯0sX) and σ(e+e−→BB¯X) in the same energy range. We measure the fraction of B0s events at Υ(10860) to be fs=(22.0+2.0−2.1)%. We determine also the ratio of the B0s inclusive branching fractions B(B0s→D0/D¯0X)/B(B0s→D±sX)=0.416±0.018±0.092. The results are obtained using the data collected with the Belle detector at the KEKB ...

Crystallization of a Na 2 O-K 2 O-Nb 2 O 5 -SiO 2 glass under thermal poling and subsequent annealing was studied by Raman spectroscopy and X-ray diffractometry. It was found that the poling and subsequent thermal treatment lead to partial crystallization of the poled region of the glass, which should be related with watering ...

Second-harmonic generation (SHG) is a well-known nonlinear spectroscopy method to probe electronic
structure, specifically, in transition metal dichalcogenide (TMDC) monolayers. This work investigates the
nonlinear dynamics of a strongly excited TMDC monolayer by solving the time evolution equations for the
density matrix. It is shown that the presence of excitons qualitatively changes the nonlinear dynamics leading,
in particular, to ...

We report the first measurement of the exclusive cross sections e+e− → 𝐵𝐵⎯⎯⎯⎯BB¯, e+e− → 𝐵𝐵⎯⎯⎯⎯∗BB¯∗, and e+e− → 𝐵∗𝐵⎯⎯⎯⎯∗B∗B¯∗ in the energy range from 10.63 GeV to 11.02 GeV. The B mesons are fully reconstructed in a large number of hadronic final states and the three channels are identified using a beam-constrained-mass variable. The shapes of the exclusive cross sections show oscillatory behavior with several maxima ...

Nafion-117/PEDOT composite membranes were synthesized by in situ chemical polymerization of 3,4-ethylenedioxythiophene (EDOT) using ammonium persulfate as an oxidant. The polymerization of EDOT in Nafion membranes for various EDOT/oxidant treatment sequences was studied for the first time. PEDOT introduction leads to a slight decrease in both the ion-exchange capacity and water uptake of the composite ...
