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.
