Laser Frequency Control System with Digital Signal Processing Techniques

摘要：

A frequency of digitally controlled iodine stabilized He-Ne laser locked to a hyperfine component in 127I2 was measured using NMIJ’s reference iodine stabilized He-Ne laser. This laser is operated under the conditions of the mise en pratique and its frequency with respect to the CIPM recommended value is known from international comparisons. Adopting a sampling rate of 120 kHz for the control system of an iodine stabilized He- Ne laser enables frequency deviation of the test laser from the reference laser by ±5kHz (relative accuracy of 1×10-11) thus limited only by the reproducibility of the iodine stabilized He-Ne laser itself.
