Fast on-line rubidium DPAL atomic concentration measurement by 420 nm probe laser: erratum

Open Access Open Access

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.

Errors have been found in Fig. 4 and a sentence of our paper [1]. In Fig. 4, the period of the probe laser should be “6 ms” rather than the marked “13 ms”. The Fig. 4 is corrected as shown here.

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.
