Based on an ideal micro-model provided for chaotic light beam,light distribution and visibility of Young s interfenrece fringes of chaotic light beam were derived by using statistical method.

Control high-intensity beam halo-chaos VIA POWER-FUNCTION FEEDBACK METHOD;

Control of beam halo-chaos by self-adaptive controlling;

Simulation study on single particle in controlling halo-chaos;

The method can be used to effectively control the beam halo-chaos.

The ratio of the numbers of ions outside the match radius to the total ion numbers,not root-mean-square radius or others,is selected as variable to simulate the control of beam halo-chaos in high intensity accelerator.

The physics of beam halo-chaos and its controlling methods are summarized , and some problems unsolved and outlooks are offered in this paper.

Optical secure communication at high bit rate with synchronized optoelectronic chaos;

Range finding with chaotic laser train generated from semiconductor lasers with optical feedback is investigated.

After considering the actually recombination mechanism of the carrier in the semiconductor,the variation of the carrier lifetime with the time has been obtained,the characteristics of the semiconductor optical chaos system have been investigated numerically,and the obtained results have b.
