Time and Frequency Activities at the CSIR National Metrology Laboratory

摘要

The CSIR National Metrology Laboratory (CSIR-NML) is the custodian of the South African national measurement standards. The Time and Frequency (TF) Laboratory is responsible for the maintenance of the SI second, which is the most accurate standard currently maintained. In addition to the maintenance of the national timescale, the TF Laboratory is also responsible for a number of other parameters, including fast electrical pulse characterization, phase angle, phase noise, and a number of fiber-optic parameters. A project in which the TF Laboratory plans to take a leading role is establishing a frequency comb based on a femtosecond laser at the CSIR-NML.
