Vacuum frequency measurement of <sup>7</sup>S<sub>3</sub>-<sup>7</sup>P<sub>4</sub> transition in Cr atoms using laser-induced fluorescence
Abstract The nanometric length traceability chain is the foundation of cutting-edge research at the nanoscale. The current traceability chain has limitations in its applications. However, the application performance of the nanometric traceability chain based on the 7 S 3 - 7 P 4 transition in chromium atoms has been fully validated. Addressing the issue that the 7 S 3 - 7 P 4 transition frequency at the traceability side of this chain has not been measured in a vacuum environment, this study used the fluorescence symmetry method under vacuum conditions to measure the 7 S 3 - 7 P 4 transition frequency, obtaining the corresponding vacuum wavelength of 425.5533474 nm and the vacuum wave number of 23498.81645 cm −1 .
