| Abstract | 飞秒激光的超快特性使其能以极低的脉冲能量获 得超强光场，并且激光辐照区淀积的能量难以通过热扩散途径逸出辐照区域，其与透明物质 相互作用是通过双光子或多光子吸收过程实现，故作用区限域于焦点核心很小体积内，因而 在三维微制备及生物医学领域有着独到优势.文章介绍了飞秒激光应用于微爆炸、高密度三 维光学数据存储、直写光波导及三维光子晶体制备、生物医学工程等方面的最新进展.飞秒 激光三维微制备技术在微电子、计算机、光通信、生物医学等高技术领域有着广阔的应用前 景. Femtosecond lasers exhibit great advantages in t hree-dimensional microfabrication and ophthalmic surgery since they can machine materials with very high resolution and precision due to their ultrashort pulse duration and ultrahigh peak intensity.Recent developments of the applications of femtosecond lasers in three-dimensional microfabrication of high density 3- D optical data storage,wave guides and photonic crystals,and in refractive sur gery,glaucoma treatment and cataract surgery are reviewed.Femtosecond laser th ree-dimensional microfabrication technology will be extensively used in microel ectronics,computer science,optical communication and biomedicine fields. |
