The robust phase locking of a linear diode array consisting of 49 broad-area emitters was demonstrated. The single lobe in the far field with output power of 0.83 W was observed. The far-field divergence was reduced to 2.0 mrad. The spectral bandwidth was
We experimentally demonstrate a three-dimensional (3D) ghost imaging method based on period diffraction correlation imaging. Compared with conventional ghost imaging, our method can easily retrieve the images of different focal planes. Due to the correlat
Upconverting lanthanide nanoparticles overcome many of the problems associated with more traditionally used luminescent contrast agents, such as photobleaching, autofluorescence, cytotoxicity and phototoxicity. For this reason, they are an attractive choi
The ablation of sintered silicon carbide ceramics by an ArF excimer laser was studied. Three zones are generated: the ablation zone that presented molten morphology and was composed by the Si and C phase; the condensation zone formed by vaporized SiC; and
