Thanks to the characteristics of ultra-short pulse width, ultra-high peak power density, and ultra-small focal spot size of femtosecond (fs) laser pulse, it could be used to achieve “heat free” precise removal/modification of any solid material. Also, with the precise optimizing of scanning strategy and fine controlling of processing parameters, various functional structures could be obtained. In the past two decades, with the improvement of laser stability and increment of repetition rate, the efficiency of fs laser micromaching has been steadily improved, which provides strong guarantees for the efficient processing of precision samples required for precision experiments. This poster mainly introduces the research progress of high-repetition-rate fs laser precision machining technology in precision experimental applications at Institute of Fluid Physics (IFP), China Academy of Engineering Physics (CAEP). The specific content includes: 1) Introduction to the research platform of high-repetition-rate fs laser precision machining technology at IFP of CAEP; 2) Research on precision structure machining technology for precise fixation of a certain micro probe; 3) Precision machining technology for core structure of terahertz (THz) filters; 4) Safe precision machining of explosives and substitute materials microstructures for dynamic experiments; 5) Research on efficient precision machining technology for compound refractive lenses (CRLs) made of super-hard material for focusing X-ray beams delivered from large-scale scientific facilities (such as XEFL and SSRF).
