Abstract

We fabricated second-order nonlinear gratings in D-shaped germanosilicate fibres using thermal poling and periodic electrodes defined by standard photolithography. These gratings, up to 75mm long, have been used for efficient quasi-phase-matched frequency doubling of 1.532µm nanosecond pulses from a high power erbium-doped fibre amplifier. Average second harmonic powers as high as 6.8mW and peak powers greater than 1.2kW at 766nm have been generated with average and peak conversion efficiencies as high as 21% and 30% respectively.
