We have measured quasiinstantaneous transverse patterns in a broad aperture laser. Nonordered patterns yielding to boundary determined regular structures in progressive time-integrated recording are observed. The linear analysis and numerical integration of the full Maxwell-Bloch equations allow us to interpret the features of the experiment. We show that this system being far from threshold cannot be fully understood with a perturbative model.
我们测量了宽孔径激光器中的准瞬时横向模式。在渐进时间积分记录中,观察到无序模式逐渐演变为边界确定的规则结构。对完整的麦克斯韦 - 布洛赫方程进行线性分析和数值积分,使我们能够解释实验特征。我们表明,该远离阈值的系统不能用微扰模型完全理解。
