Research On Two-photon Polymerization Technology Green Laser Pointer
The up-conversion green laser pointer nanoparticles used in this technology in Russia. There is the Shijianlin Group of SIIC in China. Fudan Li Fuyou Formation, Changchun Yinghua Institute Linjun Formation. Chinese people such as Qu Xiaogang Formation, Peking University's Yan Chunhua Formation, Tsinghua Li Yadong, Fu Xue Institute of Chen Xueyuan, Singapore's Liu Xiaogang, and Australia's Jin Dayong are conducting research on upconversion nanoparticles. Although with the information currently available. We still don't know whether the technology of the US National Laboratory and the Russian RAS Academy is high or low. But one thing is clear. That is, the green laser pointer two-photon curing technology has taken a big step forward.

It is the representative organization of green laser pointer engaged in the research of two-photon polymerization technology in China. Shenzhen Graduate School of Tsinghua University. During printing, a femtosecond laser generates a two-photon laser. The laser is focused through the optical path switch, the attenuator, the beam expander, the reflector and the objective lens to crosslink the photosensitive resin. And internationally, including the Technical University of Vienna, Germany, is the first enterprise and institution to develop two-photon polymerization technology. The Imperial College of Technology also printed a 100-micrometer-long model of the Great Wall of China through German equipment and presented it to President Xi. It has potential application prospects in many fields such as microelectronics, optoelectronic circuits, and regenerative medicine. Two-photon polymerization is considered by futurists to be a mainstream 3D printing form in the future. The potential scope and influence of its potential green laser pointer is quite amazing.
