Abstract—Short photonic crystal fibers (PCFs) with different tapered waist diameter are made to extend the
continuum spectrum in the visible range. The diversification of output continuum spectrum with the diameter
of the tapered waist is experimentally observed. An all fiber visible supercontinuum source with 1.88 W output
is demonstrated in our experiments. To the best of our knowledge, it is the highest all fiber visible supercontin-
uum generation in tapered PCF, pumping by picosecond pulse at 1064 nm. The suitably designed short tapered
PCF can extend the visible spectrum, while, how to preserve the tapered waist is crucial for the all fiber visible
supercontinuum source in the practical applications.
