Controlling the Orientation and Alignment of Reagent Molecules by a Polarized Laser

Process intensification (PI) is commonly seen as one of the most promising development paths for the chemical process industry and one of the most important progress areas for modern chemical engineering. Often illustrated with spectacular examples, process intensification struggles, however, with its definition and interpretation. Instead of narrowing the scientific discussion down to finding a commonly accepted definition of PI, it is more important to determine its position within chemical engineering and to identify its fundamentals. Accordingly, the paper presents a fundamental vision on process intensification. The vision encompasses four approaches in spatial, thermodynamic, functional, and temporal domains, which are used to realize four generic principles of PI. The approaches refer to all scales existing in chemical processes, from molecular to meso-and macroscale, and are illustrated with relevant examples with special attention given to the molecular scale.

We theoretically investigate the orientation of the cold KRb molecules in a weak electrostatic field assisted by a shaped laser pulse. The results show that the slow turn-on and rapid turn-off laser pulse can enhance the molecular orientation of KRb significantly, and a high degree of molecular orientation of more than 0.9 can be obtained when the electrostatic field is as low as 3 kV/cm. In addition, the influences of the electrostatic field strength and the parameters of the laser pulse are studied in detail.
