We present a highly versatile approach to the application of femtosecond Er: fiber lasers in
optical frequency metrology. Our concept relies on the implementation of two parallel …

We show that a stretched-pulse mode-locked fiber laser produces a welldefined frequency
comb, providing a compact source of frequency combs and allowing comb-based optical …

We present what is believed to be the first direct measurement of the relative timing jitter
between the two parallel pulse trains of a two-branch femtosecond erbium-doped fiber laser …

Mode-locked erbium-doped fiber lasers are ideal comb generators for optical frequency
metrology. We compare two fiber frequency combs by measuring an optical frequency …

We investigate the performance of an Er: fiber laser based femtosecond frequency comb for
precision metrological applications. Instead of an active stabilization of the comb, the …

Optical frequency combs based on erbium-doped fiber lasers are attractive tools in precision
metrology due to their inherent compactness and stability. Here we study a femtosecond Er …

We report on the measurement of an Erbium-fiber oscillator??? s carrier-envelope-offset
frequency using an extruded SF6 photonic crystal fiber for the generation of a more than two …

Optical frequency combs have revolutionized optical frequency metrology and are being
actively investigated in a number of applications outside of pure optical frequency metrology …

An ultralow-noise, subhertz 1.55 μm erbium-doped fiber laser that is locked on an all-fiber-
based Michelson interferometer is presented in this paper. The interferometer uses 500 m …

We report on a compact scheme for absolute referencing and coherent averaging for dual-
comb based spectrometers, exploiting a single continuous-wave (CW) laser in a transfer …
