分析了大菲涅耳数CO2激光器的动力学特性。我们注意到，在任何空间点处的强度远高于零，并且强度波动的平均频率与单模激光的弛豫振荡具有相同的数量级。时间振荡的互相关函数的测量显示空间相干性的损失和时空混沌的证据。
We analyze the dynamics of a CO2 laser with a large Fresnel number. We note that the intensity is much higher than zero at any spatial point and the average frequency of the intensity fluctuations is of the same order of magnitude than the relaxation oscillations of the single mode laser. Measurements of cross correlation functions of the temporal oscillations show a loss of spatial coherence and evidence of spatio-temporal chaos.
