density matrix theory meaning in Chinese
密度矩阵理论
Examples
- The key components in laser gyro is he - ne ring laser , and the reciprocal action theory between light and medium is the base in studying the ring laser , use the lamb half classical theory , and on the base of density matrix theory , the optical brounch equation was established , which described the movement of amplifying medium atom in the ring syntonic cavity , and according to the medium polarize theory the self consistent equations was deduced , which describe the light intensity and phasic of the counter - propagating wave . on the basis of this equations , adopted the simulation software matlab and virtual instrument programming language labwindows / cvi , we can do some simulated experiments in study the phenomenas such as amplify and dispersive characteristic of medium , mode pushing effection , burned hole effection and pattern competition , lock - in of frequency and the characteristic of light intensity and phasic of the counter - propagating wave in laser gyro
激光陀螺的核心部件为he - ne环形激光器，而掌握光与介质的相互作用理论是研究激光器的关键，采用拉姆半经典理论为主，在密度矩阵理论的基础上，推导环形谐振腔中描述he - ne气体增益介质原子运动的光学布洛赫方程，运用介质极化理论得出描述激光陀螺反向行波的光强、位相所满足的自洽场方程组，在此基础上，运用matlab仿真软件和虚拟仪器编程语言labwindows / cvi ，对激光陀螺中的介质增益色散特性、频率牵引效应、烧孔效应及模竞争、闭锁效应及环激光的光强和相位特性进行仿真试验研究，并且运用全量子理论，对激光工作原理进行分析，得出二能级系统单模辐射场的光子数密度分布，得出激光场的光子统计分布，仿真激光场的动态建立过程。
