抄録

We demonstrate a carrier-envelope-offset (CEO) locking of a frequency comb in the 1.5-μm band with 500-pJ laser pulse energy. To achieve the CEO locking in the 1.5-μm band with low laser pulse energy, we improve the efficiency of the laser coupling into our tellurite photonic crystal fiber using angled V-groove splicing. In addition, we use a minimum number of optics in a collinear $f$-to-$2f$ interferometer to avoid connection and propagation losses. Our method does not need any devices for group delay adjustment. Since we use a short, highly nonlinear fiber with low chromatic dispersion for octave-spanning supercontinuum (SC) generation, the group delay between the short- and long-wavelength on an octave-wide SC spectrum is about 3 ps, which does not cause serious degradation of the CEO beat signal.
