德国科学家用一超短波脉冲激光器在蓝宝石晶体中制造亚表面纳米结构,激光照射后选择刻蚀可在蓝宝石中制造微通道和自组装纳米结构,并能为化学和生物学测量创造微反应器件。以用于制造微流体装置及三维光子结构。并非用激光器对蓝宝石表面进行直接加工,研究者用在材料表面下产生的高非线性光介质相干超短波激光脉 German scientists fabricate subsurface nanostructures in sapphire crystals using an ultrashort-wave pulsed laser, selective etching after laser irradiation to create microchannels and self-assembled nanostructures in sapphire and create microreactors for chemical and biological measurements. For manufacturing microfluidic devices and three-dimensional photonic structures. Rather than laser direct processing of the sapphire surface, the researchers used in the material surface generated by the high nonlinear optical medium coherent ultrashort laser pulse
