We have demonstrated simultaneous lasing and self-frequency doubling of a neodymium and germanium doped silica fiber laser at 1.06  $\mu$m. The doubling action is provided by a self-organized phase matching grating in the fiber. The laser was modelocked using a linear external cavity which produced 600 ps pulses at 1.06  $\mu$m.
