Proposal for laser cooling of complex polyatomic molecules

Ivan Kozyryev; Louis Baum; Kyle Matsuda; John M. Doyle

An experimentally feasible strategy for direct laser cooling of polyatomic molecules with six or more atoms is presented. Our approach relies on the attachment of a metal atom to a complex molecule, where it acts as an active photon cycling site. We describe a laser cooling scheme for alkaline earth monoalkoxide free radicals taking advantage of the phase space compression of a cryogenic buffer-gas beam. Possible applications are presented including laser cooling of chiral molecules and slowing of molecular beams using coherent photon processes.

Collisional relaxation of vibrational states of SrOH with He at 2 K

Ivan Kozyryev; Louis Baum; Kyle Matsuda; Peter Olson; Boerge Hemmerling; John M. Doyle

Vibrational relaxation of strontium monohydroxide (SrOH) molecules in collisions with helium (He) at 2 K is studied. We find the diffusion cross section of SrOH at 2.2 K to be and the vibrational quenching cross section for the (100) Sr–O stretching mode to be . The resulting ratio is more than an order of magnitude smaller than for previously studied few-atom radicals (Au et al 2014 Phys. Rev. A 90 032703 ). We also determine the Franck–Condon factor for SrOH () to be .
