我们概括并测试了最近的“从头开始”自洽（AISC）时间无关的半经典激光理论。这种自洽的形式主义通过简单的输入产生多模状态中的所有稳态激光特性（频率、阈值、内部和外部场、输出功率和发射模式）：无源腔的介电函数、原子跃迁频率和激光跃迁的横向弛豫时间。我们发现，在该理论被推广到放弃缓慢变化的包络近似之后，该理论与麦克斯韦-布洛赫方程的全时间相关模拟给出了极好的定量一致性。该理论是非线性烧孔相互作用的无限阶；广泛使用的三阶近似被证明是严重失败的。 (C) 2008 美国光学学会
We generalize and test the recent "ab initio" self-consistent (AISC) time-independent semiclassical laser theory. This self-consistent formalism generates all the stationary lasing properties in the multimode regime (frequencies, thresholds, internal and external fields, output power and emission pattern) from simple inputs: the dielectric function of the passive cavity, the atomic transition frequency, and the transverse relaxation time of the lasing transition. We find that the theory gives excellent quantitative agreement with full time-dependent simulations of the Maxwell-Bloch equations after it has been generalized to drop the slowly-varying envelope approximation. The theory is infinite order in the non-linear hole-burning interaction; the widely used third order approximation is shown to fail badly. (C) 2008 Optical Society of America
