Application-Specific Optical Fibres Manufactured from Multicomponent Glasses.

Abstract

Special fibres have been fabricated to demonstrate the potential of using multicomponent glass materials for sensors, devices and fibre lasers. High nonlinearity and large Verdet constants are confirmed for lead-silicate glass fibres. Nonlinear effects such as second harmonic generation (SHG), third harmonic generation (THG), electro-optic (EO) Kerr effect and optical switching are observed for F7 core glass fibres. Compound glasses are investigated as host glasses for fibre lasers and amplifiers. An all glass cladding pumped Nd-doped fibre laser from compound glassses is characterized.

Wavelength stability of Nd 3+ -doped fibre fluorescent sources

“…Fibre 2, containing neodymium-doped alumino-phospho-silica ( 4 % Al 2 O 3 , 2% P 2 O 5 , 350ppm Nd 3+ , 7µm core diameter) and fibre 3 , containing phospho-silica (14% P 2 O 5 , 50ppm Nd 3+ , 19µm core diameter) were also examined at both room temperature and with the fibre at liquid nitrogen temperature. Fibre 4 was a compound glass fibre (NA 0.14, 5.5µm core diameter) fabricated by the rod-in-tube technique 4 and examined for spectral stability. In this case the core material was a high-gain phosphate laser glass (2wt% Nd 3+ Schott LG750) and cladding material Schott PK50.…”
