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
