Laser manufacturing, including laser surface engineering, laser welding, laser cutting, laser materials and other manufacturing as the representative of the macro manufacturing technology to high power laser pointer precision cutting, laser precision drilling, laser ablation as the representative Laser micro-processing technology, and femtosecond laser direct writing, two-photon polymerization, interference lithography, laser induced surface nanostructure as represented by laser micro-nano manufacturing technology and other broad areas of research, across the millimeter, micron and nanometer Scale, become a pivotal advanced manufacturing technology, will "2025 in China" process play an indispensable role.
Among the above research directions, laser material manufacturing and ultrafast laser micro / nano manufacturing are two hotspots of current and future research. As a typical macro-manufacturing and micro-nano manufacturing, has been desirably included in the "by material manufacturing and laser pointer manufacturing" national key R & D program, will be about 1.8 billion national research funding, the future People look forward to.
A famous American expert in the study of laser material manufacturing has said: "Large is useful, small is beautiful." He refers to the incremental material manufacturing is very useful, micro-nano manufacturing looks very attractive. If we can make useful laser material manufacturing beautiful, and make the laser micro-nano manufacturing is useful, it is an ideal state, it should be a national key R & D program to pursue the goal of it.
There is no doubt that human beings have entered the nano-world, nanoscale surface effects, small scale effects, quantum effects, and many other magical functions, given the existing macro-scale materials do not have a series of excellent performance, which is "Small is Beautiful "reason. There are many ways to enter the nano-world, in which ultra-fast laser should be a "top-down" physical methods to obtain the nanostructure of the very force and effective method.
Ultra-fast green laser pointer micro-nano manufacturing has developed very rapidly in recent years, through the laser means to prepare nano-structure of the popular direction. Ultrafast laser generally refers to picosecond and femtosecond laser with pulse width shorter than 10ps. Ultrafast laser has extremely narrow pulse width and extremely high energy density, so the time of interaction with material is extremely short. It will produce almost completely different from conventional laser processing. Mechanism, to achieve sub-micron and nano-scale manufacturing, ultra-high precision manufacturing and full material manufacturing.
Ultrafast lasers provide unprecedented manufacturing and precision manufacturing, greatly expanding the potential of laser processing and application. Especially in recent years to hundreds of femto second sub-picosecond pulse width, hundreds of kHz to MHz high repetition rate and tens of watts and even hundreds of watts of high average power for the typical characteristics of a new generation of ultra-fast burning laser pointer development is expected to solve Processing quality, precision and processing efficiency of the inherent contradiction between the usher in a new academic research and development opportunities.
