In this erratum, we correct the abstract and introduction of Opt. Lett. 43, 1742 (2018) [CrossRef] to not include a wrong name for the crystal.

In our original manuscript , we unfortunately used the wrong term “Langasite” in the abstract and in the introduction. However, Langasite is and hence a different crystal than the that was actually applied in our experiments. In order to avoid any confusion, the word “Langasite” should be removed entirely from the abstract and text. That is, in both occasions, “ (Langasite, LGS)” should be changed to “ (LGS)”. The rest of the manuscript and all results and conclusions are not affected by this change. We thank Marcus Seidel for pointing out the mistake.
