WebTo address these problems, an alternative optical-sampling approach has recently been developed. It is called optical sampling by cavity tuning (OSCAT) [25-34]. The chief goal of OSCAT is to alleviate the need for two femtosecond lasers while retaining the ability to make deep and rapid scan of the relative pulse delay. WebRecently, it was shown that asynchronous optical sampling overcomes these drawbacks as it does not require any mechanical delay lines. The technique relies on two synchronized …
