Based on theory of wave particle duality,the principal and method about making random nano-pattern by Ne atom hologram are studied. This technology can make up the disadvantage of only being able to make the periodic nano-pattern such as the single line or dot etc.when using laser gradient field to control atoms' movement to accumulate on the silicon slice.Analyzing the difference of atom hologram and optical hologram, we point out that only the laser cooling atoms can satisfy the coherent and diffract conditions...

Based on theory of wave particle duality,the principal and method about making random nano-pattern by Ne atom hologram are studied. This technology can make up the disadvantage of only being able to make the periodic nano-pattern such as the single line or dot etc.when using laser gradient field to control atoms' movement to accumulate on the silicon slice.Analyzing the difference of atom hologram and optical hologram, we point out that only the laser cooling atoms can satisfy the coherent and diffract conditions required by the hologram technology. A piece of Ne atom computer generated hologram (CGH) with Lohmann Ⅲ coding is designed and a experiment system of making random nano-pattern by controlling Ne atom beam is presented.

从波粒二象性原理出发 ,研究了用氖原子束计算全息技术制作任意纳米结构的基本原理和方法 ,克服了用激光梯度场控制原子堆积 ,只能制作单一点、线等周期性纳米结构的不足。分析讨论了原子全息与光学全息的区别 ,指出只有经激光冷却的原子束才满足全息技术所要求的相干条件和衍射条件。最后采用罗曼Ⅲ型迂回位相编码方法设计了氖原子束计算全息片 ,介绍了操纵氖原子束制作纳米任意结构的实验系统

>=we introduce a new method of frequency-shifting for a diode laser in laser cooling experiments, the method is based on Zeeman effect of 87Rb atoms. The laser frequency is stabilized by absorption spectrum line of atoms in magnetic field. We show that magnetic field can be added up to 10-2T. Corresponding frequency-shift is 102MHz and the response time is about 1ms. The large range of frequency shift is enough for laser-cooling experiments.

本文介绍了冷原子物理实验中激光移频的一种新方法——利用塞曼效应配合LIR稳频电路移频。在我们的系统中磁场可以加到10-2特斯拉量级,谱线的分裂在102MHz量级,可以满足激光冷却原子实验中移频的需要。对87Rb原子的52S1/2F=2-52P3/2饱和吸收谱线,其实际的移频范围在10MHz到70MHz之间,响应在ms量级。
