Abstract
Recently, Yb-doped fiber femtosecond optical frequency combs (Yb-FOFCs) have obtained high repetition rates and high power outputs, and the wavelengths can cover the visible region by using a photonic crystal fiber to broaden the spectrum. In this paper, f0 (carrier-envelope offset frequency) with a signal-to-noise ratio (SNR) of 40 dB is generated in an Yb-FOFC by adopting a scheme which includes the three processes of amplifying, broadening the spectrum and detecting f0, and optimizing the system parameters. The effects of two types of amplifiers which employ direct optical pulse amplification and self-similar amplification, respectively, on the output parameters of the amplifiers, minimal output power of the octave spectrum meeting f0 detection requirements, and the SNR of f0 are compared and analyzed in detail.
