We systematically study the dynamics and laser emission of randomly distributed nanoemitters (NEs) integrated into two-dimensional (2D) array of metal nanorings (NR) enhanced by the plasmon-polariton (PP) excitations. It is shown that the transition

In the environment of smoke and suspended particles, the accurate detection of targets is one of the difficulties for frequency-modulated continuous-wave (FMCW) laser fuzes to work properly in harsh conditions. To weaken and eliminate the significant

Here, the optical properties of the Nafion polymer membrane containing colloidal CdSe/CdS/ZnS nanocrystals embedded by diffusion have been studied. The CdSe/CdS/ZnS nanocrystals have a core/shell/shell appearance. All experiments were carried out at

This review describes the recent progress of floating-zone techniques for bulk single-crystal growth. The most crucial point of the crucible-free technique is to keep the molten zone stable. It has been investigated and reported to yield a steeper te

Objective: Single-mode operation is very important for laser emissivity; to exceed the emissivity of a single laser, the phase locking of all lasers in an array can be achieved only when the laser array is coupled and operated in single-mode. Methods
