Demonstration of partially transparent thick metallic sodium in the vacuum ultraviolet spectral range: reply
Abstract:
We thank the paper by Gottfried et al. [Opt. Express34, 15812 (2026)10.1364/OE.560729] for the comments on our paper, Daido et al. [Opt. Express21, 28182 (2013)10.1364/OE.21.028182]. We performed the experiment more than a decade ago. At that time, we observed "anomalous" transmission of vacuum ultraviolet (VUV) light through a sodium sample as described in our original paper. If we had obtained opaque sodium in the VUV spectral range using a few-mm-thick sodium samples, we would never have submitted a paper on this matter.
