OPTICAL FREQUENCY MEASUREMENT AT NRC AND PROGRESS TOWARDS FREQUENCY MEASUREMENT OF VISIBLE LIGHT

K. Baird

This article describes the frequency comparison chain that is being set up at N.R.C. (Ottawa) with the aim of making possible frequency measurement with respect to the Cs primary standard, of standards throughout the spectrum up to the visible region. Progress to date includes demonstration of phase locking of several stages up to 30 THz, demonstration of the feasibility of several stages from 30 THz to 260 THz and operation of the last stage from 260 THz to 520 THz (0.576 µm).
