Description
We report the fabrication of a novel high nonlinear fiber made of Ge-Sb-Se chalcogenide glasses with high numerical aperture (∼1.0), where the core and the cladding glasses consist of Ge<sub>15</sub>Sb<sub>25</sub>Se<sub>60</sub> and Ge<sub>15</sub>Sb<sub>20</sub>Se<sub>65</sub> (mol. %), respectively. The nonlinear refractive index (n<sub>2</sub>) of the core glass is 19×10<sup>-18</sup> m<sup>2</sup>/W at 1.55 μm, and its laser-induced damage threshold under irradiation of 3.0 μm fs laser is...[Show more]
