摘　　要：以一个V型的三能级原子为例,阐释激光理论的线性近似方法.当经典激光场与量子腔场共存时,若激光场的拉比频率Ω远大于耦合常数,可以将与耦合常数g相乘的算符做零阶近似,而与拉比频率相乘的算符展开到所有阶.Taking three-level V-type as an example, this paper discusses linear approximation method of laser principle. When the classical laser field and quantum cavity field coexist and the Ω Rabi frequency is much greater than the coupling constant, the operators which multiply coupling constant can be treated as approximately zero order, and the other operators which multiply the g Rabi frequency Ω can be extended to all orders.
