The experimental resuts in this paper show that the lasing threshold of rhodamine 6G solution,in which TiO2 nanocrystal aggregate is embeded,is significantly reduced compared to that of a neat dye solution.

Closed all optical cycles in optical networks may generate lasing which adversely affects network performance.

The structure growth and optimization of quantum-dot lasers are introduced firstly, then the optoelectronic properties are discussed in the term of spectrum and modeling, and the dynamic characters of quantum-dot lasers such as homogeneous broadening of optical gain, lasing spectrum control, transition property of excited state etc.

This paper discusses non-local magnetic trapping resonance effects of weakly relativistic electron on cyclotron maser in the magnetic mirrors.
