A comparative study of parameters of Quantum device

摘要

Zeeman effects are important in quantum electronics because they make possible a method by which the value of the energy level can be slightly changed, causing fine tuning of emission or absorption frequencies in optical and infrared regions. It is a theoretical approach of calculation for quantum electronic devices on the basis of semi classical theory of laser. The theory of Zeeman laser had been worked out by Lamb and his coworkers. The electromagnetic field is treated classically for a general state of polarization in a cavity with any desired degree of cavity anisotropy. The self– consistency requirement is that a quasistationary field should be sustained by the induced polarization lead to the equations which determine the amplitudes and frequencies of multimode oscillations as functions of the laser parameters. We here derived the self-consistency equations using semi classical theory of laser considering the complex conjugate terms excluded by Lamb earlier. Equations of electric field and polarization with complex conjugate terms give rise to additional equations having physical significance and terms effect on Lande’s g factor. The parameters involving utilization of the splitting of the magnetic sublevels obtained in the calculation may be utilized.
