随机激光的非平稳区

Nonstationary Regime of Random Lasers

Jonathan Andreasen, Patrick Sebbah, Christian Vanneste

摘要:

数值研究了一维和二维随机激光器随阈值以上抽运率的变化。依赖于腔模式的泄漏,我们观察到,固定激光制度变得不稳定的第二个阈值以上。相干不稳定性被观察到的总输出强度,粒子数反转和偏振的自脉动。

英文摘要:

A numerical study is presented of one-dimensional and two-dimensional random lasers as a function of the pumping rate above the threshold for lasing. Depending on the leakiness of the cavity modes, we observe that the stationary lasing regime becomes unstable above a second threshold. Coherent instabilities are observed as self pulsation of the total output intensity, population inversion, and polarization.
