In … WebAug 1, 2024 · The optical phase locked loop (OPLL) technology is used to lock not only the central frequency but also the optical phase of a laser onto a highly stable low noise laser. …
Webterm phase coherence between these sources can be achieved using an optical phase-locked loop (OPLL). In such an OPLL, the rate at which the relative phase between a master laser and a slave laser changes is locked to a fixed value f beat called the beat frequency. A number of OPLL designs have been implemented [1–5]. http://www.cchem.berkeley.edu/grfgrp/Papers/1995%20Joo%20OptLett20.pdf
