TL;DR: In this paper, the theoretical and experimental status of the intense laser alignment (EL alignment) technique is reviewed and a discussion of the physics underlying this technique and a description of methods of observing it in the laboratory is provided.

TL;DR: In this article, a polar molecule can be oriented in 3D by using a combination of laser and electrostatic fields, which should help to obtain molecular-frame information about strong-field ionization processes in molecules for which the orientation cannot be determined after ionization.

TL;DR: An unprecedented degree of laser-induced one-dimensional alignment (cos;(2)theta_(2D)=0.97) and strong orientation of state-selected iodobenzene molecules are demonstrated, enabling experiments on pure samples of polar molecules in their rotational ground state.

TL;DR: In this article, the apparent quantum yield for photobleaching has been determined for red cabbage extract at 25°C in air-saturated McIlvaine buffer, using monochromatic light at each of the irradiation wavelengths, 313, 366, and 436 nm, in continuous photolysis experiments, in order to provide an objective measure for the sensitivity of this food colorant to ultraviolet and visible light.

TL;DR: It is demonstrated, theoretically and experimentally, that an intense, elliptically polarized, nonresonant laser field can simultaneously force all three axes of a molecule to align along given axes fixed in space, thus inhibiting the free rotation in all three Euler angles.
