Abstract
A method of creating a local oscillator light beam LO for a phase-resolved spectroscopy measurement comprises the steps of providing a first measuring light beam () and a second measuring light beam () being aligned to each other, creating the local oscillator light beam LO by an optical non-linear interaction of a first portion (A) of the first measuring light beam () and a first portion (A) of the second measuring light beam () in an optical nonlinear medium (), and superimposing the local oscillator light beam LO, a second portion (B) of the first measuring light beam () and a second portion (B) of the second measuring light beam () with a predetermined mutual phase relationship, for providing a sample light beam () for the phase-resolved spectroscopy measurement. The local oscillator light beam LO and the second portions (B,B) of the first and second measuring light beams () are superimposed with a displaced Sagnac interferometer ().
