(a) One Raman laser-polarized configuration for atomic gravimeter.^[28] Red lines and blue lines represent linear polarized beams with frequencies of ω₁ and ω₂ respectively, the λ/4 plate is placed at 45° to generate circularly polarized lasers inside the vacuum chamber; (b) The blue solid line and the green dotted line represent the atomic |a, P〉 and | b, P + ℏ k_eff 〉 states in the MZ atomic gravimeter, respectively. The gray areas represent the duration time of the Raman pulses.
