  • MexFunction
    这个程序使用vc++实现的一个工程,这个工程的作用就是完整实现了MATLAB和vc++混合编程的关键函数的功能-mexfunction。有其详细的开源代码!(This program uses the vc++ implementation of a project, the role of this project is to complete implementation of the MATLAB and vc++ mixed programming function of the key functions-mexfunction. Has its open source code in detail!)

  • Monte_Carlo_simulation_cool
    说明:  蒙特卡罗模拟随机数是最好的方式,本程序设计在552nm脉冲后,再一左一右的657nm冷却脉冲,测试激发达到100 的概率,尤其考查蓝、绿及近红外波段(MATLAB 6.5 Monte Carlo simulation cool3.m This simulation cycles "num" number of atoms "steps" times, with a cooling sequence of a 657 nm cooling pulse from the right, then a 657 nm cooling pulse from the left, followed by a 552 nm quenching pulse. Then the sequence is repeated with cooling pluses first incident from the left. Switching the pulse direction order helps maintain symmetery in the resultant velocity distribution. The probability of quenching the excited state is no longer 100 , it is "percent" Random blue, IR, and green photon recoil kicks have been included in the simulation due to the quenching. )

    Photonic crystals are attractive optical materials for controlling and manipulating the flow of light. One dimensional photonic crystals are already in widespread use in the form of thin-film optics with applications ranging from low and high reflection coatings on lenses and mirrors to colour changing paints and inks. Higher dimensional photonic crystals are of great interest for both fundamental and applied research, and the two dimensional ones are beginning to find commercial applications. The first commercial products involving two-dimensionally periodic photonic crystals are already available in the form of photonic-crystal fibers, which use a microscale structure to confine light with radically different characteristics compared to conventional optical fiber for applications in nonlinear devices and guiding exotic wavelengths. The three-dimensional counterparts are still far from commercialization but may offer additional features such as optical nonlinearity require
