WebFeb 9, 2016 · 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. This is accomplished by combining laser intra-cavity modulation with an arm-length mismatched interferometer [25, 30]. Websampling (ASOPS) [18-21], dual-comb spectroscopy [22-24], and dynamic optical sampling by laser cavity tuning (OSCAT) [25-30] . They have demonstrated the feasibility or potential to reach a measurement updating rate well above 1 kHz, and in some cases, into the megahertz range [24].
