Optical Pumping of TeH+: Implications for the Search for Varying mp/me
Molecular overtone transitions provide optical frequency transitions
sensitive to variation in the proton-to-electron mass ratio (). However, robust molecular state preparation presents a challenge
critical for achieving high precision. Here, we characterize infrared and
optical-frequency broadband laser cooling schemes for TeH, a species with
multiple electronic transitions amenable to sustained laser control. Using rate
equations to simulate laser cooling population dynamics, we estimate the
fractional sensitivity to attainable using TeH. We find that laser
cooling of TeH can lead to significant improvements on current
variation limits
