日本石川岛播磨重工业公司最近利用一种新式激光发振器浓缩铀获得成功。这种方法被称为“原子法”,是目前最先进的浓缩铀的方法。与现在普遍使用的气体扩散法比较,所须费用大大降低。浓缩铀用的激光发振器是一种铜蒸汽激光发振器,即在真空放电管中使铜蒸发,利用铜 Japan’s Ishikawa Island Broadcasting Corporation has recently succeeded in enriching uranium with a new laser oscillator. This method, known as the “atomic method,” is the most advanced method of enriching uranium. Compared with the commonly used gas diffusion method, the cost is greatly reduced. The laser oscillator for uranium enrichment is a copper vapor laser oscillator, which evaporates copper in a vacuum discharge tube and uses copper
