| Abstract | |
Polar diatomic molecules present a broad range of potential applications in both basic and technological research, associated with long-range dipolar interactions and their internal structure. However, the production of dense and cold molecular samples remains highly complex due to this internal structure, requiring multiple laser sources. The development of cooling techniques applicable to any molecule is crucial for the success of this field. In this study, we theoretically and experimentally investigate the cooling of thermal molecules of 85Rb2 using broad-band laser sources. Specifically, we examine transitions between the ground-state potential X1Σg+ and the excited state B1 Πu, employing broad-band multimode diode lasers whose spectra can be manipulated using micro-mirrors. The molecular spectrum was obtained through resonant photoionization of the molecules using pulsed lasers. The results suggest that the manipulation of molecular states is achievable through optical pumping. (AU) | |
