CO $_2$ laser中的瞬态极化动力学

Transient polarization dynamics in a CO$_2$ laser

I. Leyva, E. Allaria, R. Meucci

摘要:

本文从理论和实验上研究了准各向同性CO $_2$激光器基模输出时的偏振态变化。所观察到的瞬态动力学是很好地再现通过一个模型,该模型提供了一个定量的歧视之间的内在的不对称性,由于具有不同的角动量的分子的动力学耦合,和外在的各向异性,由于一个倾斜的内腔窗口。此外,实验还对CO $_2$激光器相干项的衰减速率进行了数值赋值。

英文摘要:

We study experimentally and theoretically the polarization alternation during the switch-on transient of a quasi-isotropic CO$_2$ laser emitting on the fundamental mode. The observed transient dynamics is well reproduced by means of a model which provides a quantitative discrimination between the intrinsic asymmetry due to the kinetic coupling of molecules with different angular momenta, and the extrinsic anisotropies, due to a tilted intracavity window. Furthermore, the experiment provides a numerical assignment for the decay rate of the coherence term for a CO$_2$ laser.
