WebSep 30, 2024 · Optical pumping is a conceivable mechanism for breaking the symmetry between equivalent spin configurations in TMDs. Recent studies have shown that pumping individual monolayers or heterostructures of TMDs with circularly polarized light can generate spin imbalances with microsecond-long relaxation times ( 19 , 20 ). WebApr 12, 2024 · The optical repumping beam is resonant with 5 S1/2, F = 1 to 5 P1/2, F′ = 2 transition to pump most of the atoms to F = 2 states. Both optical pumping and repumping beams are split and sent to the two sensors (S a and S b) of the gradiometer.
