小芯径硫系玻璃光纤的制备及其非线性光学应用
Fabrication and Application of Small Core Chalcogenide Glass Fibers in Nonlinear Optics
摘要
Abstract
High purity Ge-As-Se and Ge-As-S chalcogenide glasses were synthesized by a dynamic distillation technique. Small-core step-index fibers with Ge-As-Se glass core and Ge-As-S glass cladding were fabricated through a two-step rod-in-tube approach. Supercontinuum generation was measured using a femtosecond laser as the pump. The impurities associated with C, H and O could be efficiently eliminated when Al and GaCl3 were used as the oxygen getter and C/H scavenging agent, respectively. The as-fabricated GeAsSe/GeAsS fibers have a nu-merical aperture of~1.3, and show good transmitting property in the 2–9μm spectral range. When a 22 cm long fi-ber with a core diameter of 6 µm is pumped with 4.6 kW peak power and 320 fs pulses at a repetition rate of 10.5 MHz at 4.0μm, supercontinuum spanning from~1.9 to~8.2 µm is generated with a dynamic range of ±10 dB and an average power of~4.5 mW.关键词
