High-speed wavelength-swept femtosecond source from 1055 to 1300nm using a GHz femtosecond fiber laser

摘要

In this Letter, we demonstrate a high-speed broadband wavelength-swept femtosecond source (WFS) that lever-ages the soliton self-frequency shift (SSFS) and intensity-wavelength encoding technologies. The optical wavelength of the high-speed WFS can be continuously swept from 1055nm to nearly 1300nm at a sweeping rate of 100 kHz. This WFS is especially seeded by a femtosecond mode-locked all-fiber laser at 1055nm that has a fundamental repetition rate of similar to 1.0 GHz, a maximum output power of 7 W, and a compressed pulse width of 220 fs. It is anticipated that this high-speed broadband WFS can be a promising source for applications that require fast wavelength scanning and highspeed data processing.
