Wavemeter calibration by frequency comb

Published

Author(s)

Patrick Egan

Abstract

Upgrades to the vacuum-wavelength calibration service at NIST are reported. The instrumentation centerpiece is an optical frequency comb tied to a GPS-disciplined oscillator, thereby providing direct traceability to the SI second. Historically, the service has covered lasers in the popular wavelengths red and green. Recently, capability has been added to enable the calibration of wavemeters at multiple wavelengths in the C-band telecom. For most commercially-available wavemeters, the test-uncertainty-ratio is about 10^4
