激光散射实验

The Experiment of Laser Scattering

激光的鲜明特点是能量集中的高亮度性,发散角很小的强方向性和很好的时间与空间相干性,但是在激光投影显示技术和激光惯性约束核聚变等领域又要设法消除或部分消除相干性,研制非相干激光就成为了难题。散射可能对破坏激光的相干性有些作用,可以通过简单设计加以演示,开发出新的物理实验内容。

The character of laser is high brightness of concentrated energy, strong orientation of very small launch angle and very good space-time coherence. But in some domains such as Laser Projecting Display and laser inertial constraint nuclear fusion, we have to try to eliminate the coherence or eliminate it partly. Getting the incoherent laser becomes a difficult problem over the world. It is possible that the scattering has an effect on eliminating the coherence of laser. We can show it by a simple design and develop some new contents of physical experiment of college.
