light pressure force
Examples
- Our pl spectra under hydrostatic pressure showed that the conduction band minimum is in fact the result of the interaction and mixing of the gaas conduction band states . people are still arguing that ganxas , . x ( x < 0 . 1 ) and gaas will form type - i or type - ii quantum well
通过光压力光谱的研究，我们发现gan _ xas _ ( 1 - x ) ( x 0 . 1 )的导带带边态实际上主要是gaas各导带态相互作用的结果，这为导带混合模型提供了实验的证据。 - Laser cooling and trapping rely on the interaction between laser light and atom and the transfer of energy and momentum from the optical field to the atom . using laser radiation , it is possible to decrease the atomic velocity , cool atomic gases and trap the cooled atoms
激光冷却与囚禁是基于原子与激光场相互作用，原子与光场之间产生了能量与动量交换，原子在辐射光压力的作用下，其运动速度被降低，从而达到冷却与囚禁原子的目的。 - The interaction mechanism of atomic force between tip and sample was unveiled more clearly with the analysis of the change regularity of force - distance curve . the theoretical research about the light pressure of laser and the gravity exerting on the micro - cantilever was first conducted in this paper : setting up the interacting model and formula of the light pressure , investigating the effects of these factors on the interaction mechanism of atomic force and the performance of afm , conceiving a method to remove these effects and so on . all of these were the theoretical foundation of developing the new atomic force microscopy and the new type of horizontal afm system
本文在全面分析扫描探针显微镜( spm )技术，特别是afm技术的国内外发展历史、现状及存在的主要问题的基础上，进一步揭示了afm的原子力作用机理，着重分析了力?距离曲线的变化规律；对作用在微悬臂上的光压力和微悬臂本身的重力进行了系统的理论研究和计算分析，建立了激光束对afm微悬臂的光压作用模型及计算公式，考察了这些因素对原子力作用机理及afm性能的影响；提出克服或消除这些影响的理论构想，为发展新的afm技术、研制新型afm系统提供了重要的理论依据。 - In this thesis , a semi - classical model of the force on an atom is used to describe the motion of a two - level atom interacting with a standing wave laser field . the velocity dependent force and momentum diffusion are derived through optical bloch equations by using the matrix form of the continued fraction technique . by investigating the dynamic properties of atoms in laser field , we can control and manipulate the mechanical motion of an atom
本文利用半经典理论，从二能级原子在激光驻波场中所满足的运动方程出发，推导出密度矩阵元所满足的递推关系，利用矩阵连分数方法求解出密度矩阵元，从而求出依赖于原子运动速度的光压力与动量扩散系数，通过讨论原子在激光场中的动力学行为，为原子在激光场中被囚禁、形成原子列阵以及可控制的量子态，从而为量子信息处理提供理论基础。 - If the velocity of atoms is near to zero , the light for ces will tend to confine the atoms near to nodes and antinodes . the stability depends on the magnitude of the negative slope of the light force , the depth of the potential well and the momentum diffusion coefficient . it is important to select the parameters , e . g
如果通过激光冷却能使原子速度降至很小甚至为零，光压力的作用将使原子被较稳定地囚禁于激光驻波场的节点和反节点处，其稳定程度取决于该处光压力曲线负斜率的大小、对应势能的势阱深度以及动量扩散系数的大小，因此，如何在实验中合理选择激光强度、失谐量等显得尤为关键。
