7、不思就惘,思而不学就殆Of course, there are many things to learn if I were enrolled into my ideal research field. First of all, I hope I can build up a systematic view of physics, especially in the field of optics. On the other hand, Im dreaming of the participation of some relevant projects of my major. In tha

8、t way, I can get more experiences in practice. And what is more, if it is possible, I hope I can continue to study for a doctorate degree. In a word, Im looking forward to making up a solid foundation for my future profession. 光学当中我认为最前沿的一块就是我的讨论方向：激光物理与激光技术； 自从第一台激光器红宝石激光器问世以来,光学发生了划时代的巨变； 激光由于其良好的相干性、 方向性、高亮度,在光学当中有非常广泛的应用；作为光源许多精密的光学试验都是以激光名师归纳总结 - - - - - - -第 10 页,共 10 页
