New Measurements on the Accuracy of Wavemeters

A series of two articles on the accuracy of commercial wavemeters has appeared in Applied Physics B.
The first part by Verlinde et al. is the product of a collaboration of several groups using wavemeters for nuclear-structure related research at on-line facilities. All participating groups are members of the LASPEC collaboration to perform laser spectroscopy at FAIR.
The second article by K. König et al. summarizes our experience with the “calibration” of wavelength meters with our frequency comb.
