Absolute Frequency Measurement of the R(12) 26-0 and R(106) 28-0 Transitions in 127I2 at l=543 nm
Original language description
A direct phase coherent determination of the absolute frequency of the a15 component in the R(12) 26-0 and b10 component in the R(106) 28-0 transitions in 127I2 at 543 nm has been made at the International Bureau of Weights and Measures. Lasers from theCzech Metrology Institute (Czech Republic), the National Institute of Metrology (China), the Centro Nacional de Metrologia (Mexico), the Standards, Productivity and Innovation Board (Singapore), the Centre for Metrology and Accreditation (Finland), the Danish Institute of Fundamental Metrology (Denmark), the National Physical Laboratory (U.K.), and the International Bureau of Weights and Measures took part. The mean frequency values found are f(a15) = 551 579 856 480.4 kHz, uc = 4.8 kHz and f(b10) = 551580 162 397.1 kHz, uc = 4.6 kHz for the current group of lasers, where uc is the combined standard uncertainty.
