Abstract :
In this work, the generation of as much as 236 mW single-mode second-harmonic (SH) light from a periodically poled fibre (PPSF) pumped by a high power fibre laser is demonstrated. The PPSF device was fabricated by the insertion of wire electrodes into the holes of a specialty twin-hole germanosilicate fibre. The acceptance bandwidth of the device was measured to be 0.46 nm in agreement with theoretical predictions. From this measurement, the normalised conversion efficiency was estimated to be 7.34x10-2%/W.
