四能级系统 meaning in Chinese
four level system
four-level laser system
Examples
- Atomic coherence effects in four - level system
四能级系统中的原子相干效应 - Evolution of the entropy of a two - mode field interacting with a casade three - level atom system
型四能级系统互作用光场的熵演化 - The research work primarily concludes as follows : 1 . the steady rate equations are get under the analysis of four energy class of yb3 + , and the approximate resolution is carried out
研究工作主要包括: 1 、分析了镱离子工作的四能级系统,在近似求解稳态速率方程组的基础上得出了光纤激光器输出功率的解析表达式,并且计算了解析解与数值解的偏差。 - First , we study electromagnetically induced absorption . this significant feature of the system model is that a four - level system in which three - dipole transitions are in n configuration in this system , the middle transition serves as a probe transition and two other transitions serve as couple transitions
系统的模型特征是：三个电偶极跃迁构成n型链的四能级系统，其中，中间跃迁为探测跃迁，两边的跃迁为耦合跃迁。 - In the second chapter , the operating principle of solid - state laser is analyzed . based on the model of four - level system , the interacting theory between laser field and laser crystal is studied by the rate equation theory , then the characters , such as threshold power , output power , slope efficiency etc . , of solid - state laser are deduced
