Abstract
In this work, we investigated a new procedure for preparation of purified As-Se glass. After drawing the fibers, an unclad fiber with minimum loss of 2.2â¯dB/m and a fiber coated with polyether sulfone with minimum loss of 4.2â¯dB/m were obtained. By pumping the unclad glass fiber in the normal dispersion region at 3â¯Î¼m, the broadest supercontinuum generation spectrum, covering 1.6â¯Î¼m to 11â¯Î¼m with a 40â¯dB spectral flatness, was recorded from a 15â¯cm long fiber. The results showed that broadband SC covering nearly almost all transmittance of the material can be achieved with a pump laser in the normal dispersion region.
