Paper Abstract

We have succeeded in synthesizing zinc oxide (ZnO) microspherical crystals and Silicon microspheres by a simple laser ablation technique in air, and demonstrated whispering-gallery-mode (WGM) lasing from optically-pumped ZnO microsphere. ZnO/MgO alloy microspheres were also successfully fabricated, and blue-shift of WGM lasing wavelength was achieved. Recently, size-controlled and on-demand fabrication of semiconductor microspheres by introducing of an optical vortex beam.
