| 摘 要： | 从激光调Q速率方程出发,分析推导了激光调Q过程中,腔内光子数与工作物质内反转粒子数间的关系.再根据激光调Q的过程中,对腔Q值控制方式不同,将激光调Q技术分为:转镜调Q、声光调Q、电光调Q、饱和吸收调Q和脉冲透射式调Q.用C语言进行了激光调Q CAI软件的开发研制,获得了将文学、图形、动画和计算融为一体的,直观而生动地将调Q的理论和过程再现于屏幕的CAI课件.介绍了课件的内容、结构及其特点. |

| Abstract: | The relation is deduced both photon number in the resonator and population inversion in the laser medium,from rate equations of Q modulation.The laser Q switch is divided into rotating mirror Q switch,acoustooptical Q switch,electrooptical Q switch,saturable absorber Q switch and pulse-transmission mode Q switch.The software of laser Q modulation CAI is developed to make use of C language according to theory of Q switch.The theory and process of Q switch is displayed intuitively and brilliantly by means of characters,images,animations and calculation on screen.The content,construction and characteristic of the CAI courseware for Q moaulation are introduced. |
| Keywords: | Laser Q modulation Photon number Population inversion CAI |
