具有无噪声真空库的两能级Laser动力学

Two-Level Laser Dynamics with a Noiseless Vacuum Reservoir

Fesseha Kassahun

摘要:

本文分析了封闭腔中的二能级原子通过电子轰击被抽运到上能级的二能级激光器所产生的光的量子特性。我们考虑的情况下,两个能级激光器耦合到一个真空水库通过一个单端口镜,并试图进行我们的分析,把正常秩序的噪声运营商与真空水库。研究发现,当工作在阈值以上时,二能级激光器产生相干光,当工作在阈值时,产生混沌光。此外,我们已经确定,总平均光子数的很大一部分被限制在一个相对较小的频率间隔。

英文摘要:

We analyze the quantum properties of the light generated by a two-level laser in which the two-level atoms available in a closed cavity are pumped to the upper level by means of electron bombardment. We consider the case in which the two-level laser is coupled to a vacuum reservoir via a single-port mirror and seek to carry out our analysis by putting the noise operators associated with the vacuum reservoir in normal order. It is found that the two-level laser generates coherent light when operating well above threshold and chaotic light when operating at threshold. Moreover, we have established that a large part of the total mean photon number is confined in a relatively small frequency interval.
