We present an experimental treatment for the supercontinuum (SC) generated through a photonic band-gap fiber by a sub-microsecond pulse launched from a gain-switched 1126-nm fiber laser. The SC spectrally spans over a half-octave (~1.0-1.6 μm) and is attainable yet at fairly moderate fiber length (tens of cm). The SC generation process is shown to originate from silica nodes of the fiber cladding ("secondary cores"), where the pump radiation is tightly focused, and to be triggered out by a four -wave mixing process, which is boosted up by the Raman response in the fiber.
