Furthermore, developing laser application in nanomaterial; synthesis is also an unique area. It is worth further studying the; design and fabrication of nanostructured materials. Last but not least,; it is interesting to explore the specifi cproces san dcharacteristic so; flaser processing, which play an important role in advanced; manufacturing. In precision engineering, the tool of laser has also been; more applicable considering its great advantages in microprocessing and; nanofabrication. Several case studies are introduced, which have great; potential and high impact applications, such as ultrafast laser direct; writing, laser micro-lens lithography, laser nanofabrication to break; through optical diffraction limit and hybrid micro/nanostructures with; unique functions fabricated by laser. These studies have triggered; intensive research interests due to their great application prospect.国家自然科学基金; 国家重点基础研究发展计划; 温州大学激光加工机器人省重点实验室开放基金;; 中国科学院光电技术研究所微细加工光学技术国家重点实验室开放课题; 福建省科技厅引进重大研发机构资助项
