Efficient all-fibre frequency doubling of 1.5 µm pulsed fibre laser has been demonstrated. 3.6 mW of second-harmonic light in fundamental mode was produced by quasi-phase-matching in a 11.5 cm long periodically poled germanosilicate fibre. The χ(2)-grating was fabricated by continuous periodic-UV-erasure
