Metallic 2H-Tantalum Selenide Nanomaterials as Saturable Absorber for Dual-Wavelength Q-Switched Fiber Laser
A novel 2H-phase transition metal dichalcogenide (TMD)–tantalum selenide (TaSe<sub>2</sub>) with metallic bandgap structure is a potential photoelectric material. A band structure simulation of TaSe<sub>2</sub> via ab initio method indicated its metallic property. An effectiv...

A novel 2H-phase transition metal dichalcogenide (TMD)–tantalum selenide (TaSe<sub>2</sub>) with metallic bandgap structure is a potential photoelectric material. A band structure simulation of TaSe<sub>2</sub> via ab initio method indicated its metallic property. An effective multilayered TaSe<sub>2</sub> saturable absorber (SA) was fabricated using liquid-phase exfoliation and optically driven deposition. The prepared 2H–TaSe<sub>2</sub> SA was successfully used for a dual-wavelength Q-switched fiber laser with the minimum pulse width of 2.95 μs and the maximum peak power of 64 W. The repetition rate of the maximum pulse energy of 89.9 kHz was at the level of 188.9 nJ. The metallic 2H–TaSe<sub>2</sub> with satisfactory saturable absorbing capability is a promising candidate for pulsed laser applications. |
