Correction to: Nature Communications 10.1038/s41467-023-43367-z, published online 06 December 2023

The original version of the published Article had incorrect assignment of references in Table 1 (see below)

Table 1.

Performance of comparable cavity ring-down spectrometers operating near 4.5 μm

Reference	α0 at 1 s (cm−1 Hz−1/2)	L (m)	α0 at 1 s for L = 10 cm (cm−1 Hz−1/2)

Here the absorption coefficient at 1 s integration, cavity length, and normalized performance for each system are shown. The ultralow optical loss of our crystalline coatings yields the lowest normalized noise-equivalent absorption.

For reading Table 1 correctly, the following list of reference changes are applicable

• In Line 1, INO-CNR – reference changes from 18 to 20

• Line 2, VTT – reference changes from 19 to 21

• Line 3, Nagoya – reference changes from 20 to 22

• Line 4, NIST – reference changes from 21 to 23

• Line 5, LLNL – reference changes from 15&22 to 17&24, respectively.
