3D TiO₂ nanobipyramids (TiO₂-NPs) and 1D TiO₂ nanobelts (TiO₂-NBs) were synthesized from potassium titanate K₂Ti₆O₁₃ and characterized by X-ray diffraction (XRD) patterns, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), selected area electron diffraction… (More)
A mode-locked Tm-Ho-codoped silicate fiber laser with a Sb-based SESAM is reported. The fiber laser generates mode-locked solitons at 2.06 μm with pulse energy of 0.41 nJ and pulse duration of 1.1 ps.
This thesis is devoted to the study of transverse modes in large-mode-area (LMA) fibers. It highlights the importance of transverse spatial-hole burning (TSHB) effect in LMA multimode fibers through experiments and simulations. The measured beam-quality factor decreases until the gain becomes saturated in an amplified spontaneous emission (ASE) source based… (More)
