Abstract
A single-loop method of phase locking up to 100 GHz is described. Spectral broadening observed in harmonic mixing with an HCN laser at 891 GHz (with resolution 1 in 108) is attributed to phase noise and modulation on the base-reference quartz-crystal oscillator. Zero beats at 99 GHz between klystrons phase-locked to a common reference give frequency resolution of the order of 1 in 1013.Keywords
