Optical sampling by laser cavity tuning
Webcoherent optical sampling method.19) The laser cavity length was controlled by a piezo-electric device to switch the scan direction from upward to downward. Kim et al., suggested an electronically controlled optical sampling technique, which uses laser repetition frequency modulation by cavity tuning.20) The disadvantage of this method is that the
