我们已经开发了一个理论模型，使我们能够研究的情况下，碰撞加宽的洛伦兹线形状的超荧光脉冲的延迟时间统计。我们的模型基于更稳健的延迟时间定义，基于能量而不是强度参考。我们计算的概率分布的延迟时间在超荧光的起始制度，反转基本上是恒定的。我们发现，随着碰撞退相速率的增加，平均延迟时间增加，分布变宽。我们比较了我们的结果与非均匀加宽的洛伦兹线形的情况下，发现意外的结果，统计行为是相同的。
We have developed a theoretical model that allows us to study the delay-time statistics of superfluorescent pulses for the case of collisional broadening with a Lorentzian line shape. Our model is based upon a more robust definition of delay time, based upon an energy rather than an intensity reference. We calculate the probability distribution of delay times in the initiation regime of superfluorescence, where the inversion is essentially constant. We find that, as the collisional dephasing rate is increased, the mean delay time increases and the distribution broadens. We compare our results with those for the case of inhomogeneous broadening with a Lorentzian line shape and find the unexpected result that the statistical behavior is identical.
