Abstract
We present an erratum to our Letter [Opt. Lett. 47, 3688 (2022) [CrossRef] ]. This erratum corrects subscript errors in Eq. (1), H1 and H2. These errors could confuse readers when they perform the derivation processes, but the errors do not affect our experimental results. Therefore, these corrections do not affect the results and conclusions of the original Letter.

Our original Letter [1] contained three errors: Eq. (1), and the expressions of $H_{1}$ and $H_{2}$.
The correct equation (1) is
The correct expression of $H_{1}$ is $H_{1}=h_{cf}\rho _{f}\eta _{f}$, and the correct expression of $H_{2}$ is $H_{2}=h_{cr}\rho _{r}\eta _{r}$.These errors could confuse readers when they perform the derivation processes, but the errors do not affect our experimental results. Therefore, these corrections do not affect the results and conclusions of the original Letter.
