Research output: Contribution to journalConference articlepeer-review


We report on the features of our compact iodine-stabilized 543 nm He-Ne lasers and the corresponding 27I2 hyperfine transitions. The stability, reproducibility and resettability are investigated; the frequency intervals of the resolved hyperfine peaks are measured thus the corresponding hyperfine constants are determined; the linewidth of each main line is measured; the features of the suggested wavelength standard line b10 are investigated in details for the first time.
