Selecting the Best Ultrashort-Pulse Laser for Polymer Processing

This technical report discusses the application of ultrashort-pulse (USP) lasers in the medical device manufacturing industry, specifically for polymer processing. It outlines the increasing demand for precise machining of materials such as stents and catheters, highlighting the advantages of USP lasers due to their reliability and cost-effectiveness. The report details key laser parameters including pulse width, energy, and frequency, emphasizing the superiority of femtosecond lasers for achieving high-quality features without melting. Testing results indicate that optimal pulse energy levels range from 40 to 100 µJ, with higher frequencies providing better removal rates. Additionally, the report compares the effectiveness of different wavelengths, concluding that green and ultraviolet wavelengths yield better surface finishes and processing windows. The findings underscore the importance of tailored testing for specific applications to ensure optimal laser selection based on production requirements.
