Core/shell CdSe/ZnS quantum dots (QDs) are synthesized by thermal deposition using cadmium oxide and selenium as precursors for a hot lauric acid and hexadecylamine trioctylphosphine oxide hybrid. The CdSe/ZnS QDs show high photoluminescence efficiency, w
Diode-pumped acousto-optic Q-switched pulse laser at 1.5–1.6 \mu m is obtained in an Er3 :Yb3 :LuAl3(BO3)4 crystal. Single-pulse laser operation with slope efficiency of 14% and threshold of approximately 100 mW is realized at an average absorbed pump po
Anisotropic dewetting polydimethylsiloxane (PDMS) surfaces, which consist of groove-like micro/nanostructures (so-called hierarchical structures), are fabricated using an ultrashort pulsed laser. The contact angles (CAs) are measured parallel to the micro
