Abstract: We achieved efficient frequency conversion from a 1064 nm subnanosecond pulse pump to a dispersive wave (DW) centered around 1535 nm in a microstructured double core fiber. We experimentally observed that at the output of a 4 m span of fiber almost half of the input pump power was transferred to a 100 nm band around the peak of the DW. Such outstanding conversion efficiency is an outcome of the fiber dispersion curve exhibiting a large normal peak around 1515 nm, which allows for the resonant energy transfer into the DW directly from the solitons which are generated nearby the pump wavelength.
