Abstract
The frequency of a primary subterahertz oscillator has been phase locked with the use of the equidistant components of a broad spectrum produced by a femtosecond laser. The optical-to-terahertz down-conversion of the laser pulse train and its mixing with subterahertz radiation has been performed at a Schottky diode. This work provides the opportunity of creating a principally new generation of frequency synthesizers with the desired power and phase noise a few orders of magnitude lower than that of their traditional analogues.
