Supercontinuum Generation Pump By a Molybdenum Disulfide Based Soliton Mode-Locked Fiber Laser

Abstract

In this letter, a highly stable soliton mode-locked Erbium-doped fiber laser (EDFL) is passively obtained using a molybdenum disulfide (MoS2) thin film as a saturable absorber (SA). The MoS2 thin film obtained via electrochemical deposition technique is integrated into an EDFL cavity to generate mode-locked pulses operating at 1.88 MHz with a pulse duration of 3.03 ps. Supercontinuum (SC) light is generated using the proposed soliton mode pulses operating at 1560.4 nm as they are injected into a 100 m long highly nonlinear photonic crystal fiber (HN-PCF) after it is amplified to the output power of 17.8 dBm. The SC light operates in a wavelength range starting from 1360 nm to more than 1750 nm with the intensity above -35 dBm. The proposed supercontinuum laser can be seen as a promising light source for metrology and sensing applications.
