The probe transmission signal in the MOT used for fine alignment of probe light. The coupling light is blocked and the laser is scanned across the transition 5²S_1/2, F = 2 → 5²P_3/2, F′ = 1, 2, 3 using PZT. The three absorption peaks correspond to the transition |F = 2〉 → |F′ = 1〉, |F = 2〉 → |F′ = 2〉, and |F = 2〉 → |F′ = 3〉. The absorption of the transition |F = 2〉 → |F′ = 2〉 used for EIT experiment is about 60%.
