Abstract :
In this letter, we discuss the technology of a thin-film coating made with electron beam evaporation on a single-mode fiber end facet. A dichroic mirror made of ZrO2 and SiO2 was found to provide the necessary selectivity for 980-nm pump and 1040-nm signal wavelengths and enabled us to build a short-cavity mode-locked ytterbium fiber laser. Combined with a photonic crystal fiber dispersion compensator, it allows the realization of a 572-fs soliton all-fiber laser with a fundamental repetition rate of 571 MHz.
