High-Precise Measurement of Optical Rotatory Dispersion Based on Weak Value Amplification

IEEE Photonics Journal, 2021
Chiroptical signals (generally very weak) play significant roles in chiral discrimination that bring great benefits in biochemistry, pharmacy, chemical, and so on. But, high-precise chiroptical detection is still a challenge.

State- and molecule-selective rotational control in gas mixtures with a shaped optical centrifuge [PDF]

, 2021
We demonstrate experimentally a method of all-optical selective rotational control in gas mixtures. Using an optical centrifuge - an intense laser pulse whose linear polarization rotates at an accelerated rate, we simultaneously excite two different molecular species to two different rotational frequencies of choice.

Synthesis and luminescent properties of novel red-emitting Eu(III) complexes based on alanine aliphatic derivatives with different optical rotation

Materials Research Express, 2020
A series of novel luminescent amino acid-rare earth complexes (denoted as Eu(L/D-SA) _3 -Phen) have been successfully synthesized. Using stearoyl alanine (denoted as SA) with different optical rotations as the first ligand and 1,10-phenanthroline (Phen ...
