国外新发明新产品速变蓝激光美国ＩＢＭ公司和Ｐｕｒｄｕ大学、Ｂｒｏｗｎ大学的研究人员合作，发明了一项可使红色激光迅速转变为蓝色激光的专利萨术。在光学领域中，人们知道，蓝色激光要比红色激光的波长更短，因而其应用范围要比红色激光更大，更能适合担负精密细巧的... Foreign new inventions and new products Rapid-change blue lasers IBM, in collaboration with researchers from Purdu University and Brown University, invented a patented saxophony that quickly turns red lasers into blue lasers. In the field of optics, people know that the blue laser is shorter than the wavelength of the red laser, so its application range is bigger than the red laser, and it can be more suitable for taking care of precision....
