An optical frequency comb is a laser source with a comb-like spectra consisting of equally spaced modes in the frequency domain and is widely used in measurement and spectroscopy. In spectroscopic applications, achieving a high repetition rate is important to secure sufficient power per comb mode. We developed an all-polarization-maintaining Figure-9 optical frequency comb with a repetition rate of 206 MHz; however, its stability was limited by the insufficient control bandwidth of the piezoelectric actuator. To overcome this issue, we are developing an EOM-integrated Figure-9 fiber laser frequency comb that enables broadband control while maintaining a high repetition rate. In this work, we achieved beat frequency (fbeat) stabilization with a reference laser and detection of the carrier-envelope offset frequency (fceo).
