摘要

Experimental verification is given for self-stabilization of the carrier-envelope phase (CEP) of idler pulses from a noncollinear optical parametric amplifier. The verification is performed by spectral interference (SI) between an octave-broadened supercontinuum (SC) and its second harmonic. This SC is generated by nonlinear propagation of the second harmonic of the idler through a photonic crystal fiber (PCF). Although the modulational instability causes the intensity and CEP fluctuation and the amplified spontaneous emission noise in PCF degrades the visibility of SI, the CEP is verified to be stabilized.
