Abstract :
Second harmonic conversion efficiencies of 3*10-4 in tantalum doped silica fibres prepared by the seeding technique are reported. A series of experiments were conducted to characterise the frequency doubling in this fibre and to compare the results to the behavior observed in germanosilicate and rare earth doped aluminosilicate fibres.
