光子源研究的一般目标之一是产生比现有光源更亮、更相干的辐射，或产生脉冲更短或波长更短的辐射。为此，同时开展了对最小激光器和最大同步辐射源的研究。法国格勒诺布尔欧洲同步辐射实验室小组和美国劳仑斯·伯克利国家实验室小组最近在这两个方向上取得重大进展。同步辐射 One of the general goals of photon source research is to produce brighter, more coherent radiation than existing light sources or to produce radiation with shorter pulses or shorter wavelengths. To this end, at the same time carried out on the smallest laser and maximum synchrotron radiation source research. The Group of European Synchrotron Radiation Laboratory in Grenoble, France, and the Lawrence Berkeley National Laboratory Team in the United States have made significant strides in both directions recently.
