Abstract

A saturable absorber (SA) based on molybdenum sulfoselenide (MoSSe) was fabricated using a combination of liquid exfoliation and laser deposition methods. A dual-wavelength passively Q-switched Er-doped fiber laser (EDFL) was fabricated by inserting the MoSSe-SA into a ring cavity. The maximum average output power was 23.4 mW. The pulse width decreased from 2.8 to 1.78 μs while the corresponding pulse repetition rate increased from 50 to 90 kHz. To the best of our knowledge, this is the first report on a passively Q-switched EDFL based on a MoSSe-SA operating at 1.5 μm. Our results indicate that MoSSe-like three-element transition-metal dichalcogenides could be a promising alternative optical modulators for pulsed fiber laser generation.
