All polarization-maintaining wavelength tunable mode-locked ytterbium-doped fiber laser

Abstract

Ultrashort pulse lasers have the characteristics of narrow output pulse width, high peak power and wide spectrum, and are widely used in precision manufacturing, biomedical, quantum communication, national defense and military. In actual production and life, the wavelength tuning and switching of mode-locked fiber lasers have important applications. In this paper, we demonstrate a wavelength-tunable mode-locked fiber laser, which is a mode-locked ytterbium fiber laser working at 10.84MHz, and achieves wavelength-tuned output in the range of 1017~1029nm by adding tunable devices. This tunable and short pulse all-fiber laser has the advantages of simple structure, easy tuning, and good stability, and has a wide range of application prospects.
