Self-referenced optical frequency comb based on low-noise Yb:CALGO femtosecond laser system

We report on the design, realization and characterization of a compact optical-frequency-comb operating in the wavelength range from 670 to 1500 nm, based on a diode-pumped low-noise Yb:CALGO amplified ultrafast laser system. Both the carrier envelope offset and repetition rate frequencies are phase-locked to reference synthesizers providing a long-term fractional frequency stability of 7 × 10−13 at 100 s integration time.
