标题： Studies on particle creation during the universe expansion with a laser system

摘要： 当两束高度强激光束碰撞时，它们产生一个折射率变化非常快的区域，从而产生光子。 折射率的变化类似于宇宙尺度因子的变化。 因此，这种激光系统可以作为宇宙膨胀的类比。 我们发现，在可行的条件下可以产生几百个光子。 该系统可以演示暴胀或其他类似时期中的粒子产生。 显示英文摘要

摘要： While two highly intensive laser beams collide, they create a region where the refractive index varies so quickly that photons are created. The variance of the refractive index is analog to the universe scale factor variance. Therefore, this laser system can be an analog to the expansion of the universe. We find that several hundreds of photons can be created under feasible conditions. This system can demonstrate the particle creation during inflation or other similar periods.
