We fabricated a core-cladding Ge?Sb?Se glass fiber with a Ge12.5Sb15Se72.5 core and Ge15Sb10Se75 cladding, achieved a supercontinuum spectrum spanning from 2 µm to 9 µm by pumping the Ge?Sb?Se fiber with a core diameter of 11 µm using a femtosecond laser...

Conical emission is a typical nonlinear phenomenon that occurs during the filamentation of femtosecond laser pulses in transparent media. In this work, the conical emission induced by two kinds of typical vortex beams (i.e., Laguerre?Gaussian (LG) and Be...
