The application of femtosecond lasers in the industrial field is becoming increasingly widespread and important. Its pulse duration is extremely short (1 femtosecond=10 ^ -15 seconds), and its peak power is extremely high. This brings about a key feature: 'cold working' or 'no heat working'.
Based on this core advantage, the main applications of femtosecond lasers in industry can be divided into the following categories:
1. Precision drilling and cutting: Medical stents, cutting nozzle drilling, sapphire glass cutting, flexible circuit board (FPC) cutting, etc.
2. Surface microstructure processing and texture: Superhydrophobic/superhydrophilic surface, friction reducing and wear-resistant surface, structural color, enhanced biocompatibility.
3. Internal 3D processing and modification: Welding inside the glass, selective cutting inside the glass, manufacturing of optical waveguides, and data storage.
4. Film processing and peeling: OLED display panel repair, solar cell marking, flexible electronic manufacturing.
5. Other special applications: Composite material processing: cleaning and paint removal.
In summary, femtosecond lasers are currently one of the "ultimate tools" in the field of industrial precision machining. It is rapidly penetrating from early laboratory and medical fields to industrial fields such as consumer electronics, new energy vehicles, semiconductors, and high-end manufacturing, providing new solutions to problems that traditional processing methods cannot overcome.
