Wavelength-meter calibration across the Atlantic

2021/07/29

To support collinear laser spectroscopy measurements of short-lived proton-rich nickel isotopes with the BECOLA experiment at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University (MSU), we measured absolute transition frequencies of three iodine lines in the 700-nm wavelength range with our frequency comb. Using similar setups on both sides of the Atlantic, we were able to calibrate a wavelength meter at MSU and to correct an offset of approximately 11 MHz with an accuracy of 1 MHz. The calibration measurements at the IKP were performed within the Bachelor Thesis of Julian Palmes.
