| Abstract: | |
In this paper we investigate the feasibility of Zeeman slowing calcium monofluoride moleculesoriginating from a cryogenic buffer gas cell. We measure the A^2Π1/2(v = 0, J = 12 ) − X^2Σ1/2(v = 0, N = 1) hyperfine spectrum of CaF in the Paschen–Back regime and find excellentagreement with theory. We then investigate the scattering rate of the molecules in a molecularZeeman slower by illuminating them with light from a 10 mW broad repumper and a 10 mWmulti-frequency slowing laser. By comparing our results to theory we can calculate the photonscattering rate at higher powers, leading to a force profile for Zeeman slowing. We show resultsfrom a simple 1D simulation demonstrating that this force is narrow enough in velocity space tolead to significant velocity compression, and slowing of the molecules to trappable velocities. | |
