Electronically tunable mid-infrared mode-locked dysprosium fiber laser with over 330 nm tunability [Invited]. Proc. SPIE 10897, Fiber Lasers XVI: Technology and Systems, San Francisco, USA, 2019, (Paper 108970R).
Abstract
Mode-locked fiber lasers are currently limited to sub-3-µm wavelengths, despite application-driven demand for longer wavelength mid-IR pulse sources. Erbium- and holmium-doped fluoride fiber lasers are emerging for 2.7–2.9 µm emission, yet further extending this coverage is challenging. Here, we propose a new approach using dysprosium-doped fiber with frequency shifted feedback (FSF), achieving 33 ps pulses with up to 2.7 nJ energy, tunable from 2.97 to 3.30 µm. Notably, this is the longest wavelength mode-locked fiber laser and the most broadly tunable pulsed fiber source to date. Simulations are also performed, offering insights into the dynamics of FSF pulse generation.
