摘要: We designed and fabricated a tellurite (76.5TeO2-6Bi2O3-11.5Li2O-6ZnO, mol. %) microstructured optical fiber (TMOF) with four air holes for widely tunable third-harmonic generation (THG). The loss of the TMOF is ∼0.2 dB/m at 1550 nm. Widely THG from ∼567 to 902 nm obtained when pumped by an parametric oscillator pump wavelength changing ∼1700 2700 nm. mechanism in this work further investigated through signal pattern, which due high nonlinearity power, not phase-matching process between fundamental mode high-order TH mode.
