Within the last few years, a robust market has developed for femtosecond laser sources and application processes that enable precision micro-machining with high speed, consistency and reliability in factories around the world—where temperature, humidity, debris and handling conditions rule out the use of conventional, scientific grade femtosecond laser systems. Femtosecond lasers for precision industrial micro-machining must meet several simultaneous criteria to enable technical feasibility and clear economic benefit to the end-user. We will detail the applications in consumer electronics, automotive and medical device manufacturing that are defining the market requirements for this most precise micro-machining tool, describe the design and performance of our industrial grade femtosecond fiber lasers, and highlight the technical breakthroughs that enable unprecedented micro-machining system performance level.
