激光新阈值理论 临界增益饱和 振荡放大持续时间 new threshold theory of laser critical gain saturation duration of oscillation and amplification
摘要
本文对激光的阈值给出了新的理论解释,提出了激光新阈值理论.导出了激光新阈值条件的解析表达式,并对各类激光器分别进行了讨论.而且从实验上测量了激光器的阈值反转粒子数密度nth与允许激光器获得振荡放大的持续时间Δt之间的关系,其结果与激光新阈值理论结果相一致.
Abstract
In this paper a new threshold theory of laser is given and analytical formula of the theory is introduced. The threshold values for some kinds of lasers are discussed. The relationship between the threshold inversion and the oscillating duration is investigated experimentally. And the measured result is in good agreement with that of the new threshold theory of laser.
