Abstract

In this work we present first time domain all optical investigations of a single double-clamped Si3N4 cantilever resonator, using high speed asynchronous optical sampling (ASOPS). This method is based on two asynchronously linked femto-second unidirectional ring lasers of 1 GHz repetition rate. One laser provides the pump pulse while the other provides the probe pulse. The time delay is realized by introducing a 5 kHz offset in the repetition rates of the two lasers without requiring a mechanical delay line [1,2].
