Abstract
We present an erratum to our recent work [Appl. Opt. 60, 10862 (2021) [CrossRef] ] that corrects errors in Fig. 4 and the body of the paper. The corrections do not affect the results and conclusions of the original paper.

Fig. 4. Signal of 420 nm probe laser, 795 nm Rb laser, and the 780 nm pump laser when the DPALs are operating.
In Section 3, “The 420 nm probe laser is a square wave signal with a pulse width of 3 ms and a period of 13 ms, which is sufficient longer than pump pulse and controlled by the chopper 1” should be corrected as: “The 420 nm probe laser is a square wave signal with a pulse width of 3 ms and a period of 6 ms, which is sufficient longer than pump pulse and controlled by the chopper 1.”
The errors do not influence the results and conclusions of the original paper.
