Advanced Photonic Crystals (APC) has developed a U.S. patented hydrothermal crystal growth process to produce the KBBF crystal here in the United States, becoming the nation’s only domestic source of this strategic material. The samples evaluated and tested to date have demonstrated that APC’s KBBF crystals are comparable to, and in many parameters exceed, the quality of the Chinese equivalents, and they can be produced at significantly lower cost.
对英语不好的吧友,这段话的主要意思是:APC已经开发出有完全知识产权的KBBF晶体,是美国国内唯一能够生产这种战略性物质的唯一厂家,其产品已经达到,在某些方面甚至超过中帝的产品,而且价格远远低于中帝的产品!而且价格远远低于中帝的产品!而且价格远远低于中帝的产品!
KBBF全称为氟硼酸铍钾,化学式为KBe2BO3F2,是一种非线性无机光学晶体,有中国科学院理化所经过15年的研究开发成功。这种晶体可以将比较容易产生的激光转化为高频的、接近紫外的激光。2009年,中国意识到了KBBF的战略重要性,就对全世界实行了贸易封锁。著名的“自然”杂志在2009年非常不同凡响地发了一篇很长的社论(http://不敢发链接),为这个封锁而痛心疾首。这篇文章里提到的第一个美国科学家在2009年之前通过合作得到了一个KBBF晶体,然后就珍藏起来,只用于最重要的实验,因为这种晶体有一定的使用寿命。
我们强烈呼吁中国政府检查一下是否有美国留学生在理化所窃取了这个技术,或者是美国政府、军方通过网络攻击下载了理化所的实验记录,严厉谴责美国人不遵守普世规则的行为!
KBBF’s Deep UV characteristics can enable:
?Improved detection of airborne chemical and biological agents
?Enhanced detection of explosives and explosive residuals
?Significant improvement in the ability to inspect microchips with solid state metrology
?Advanced research and development of new superconductor materials and applications
KBBF has up to twice the UV performance of BBO in high power, ultrafast laser applications. For improved U.S. defense and homeland security threat detection, for rejuvenating U.S. superconductor research, and for enabling enhanced metrology capabilities, KBBF is a “game changer”.
