Abstract
Ultra-short pulse lasers have become indispensable in industrial and scientific micro-processing applications, offering advantages like surface texturing, treatment, drilling, and micro-welding. However, these applications also present unique challenges, including process speed, precision, and seamless integration into industries. This paper explores how beam shaping addresses these challenges in micro-processing. Various beam shapes, such as beam splitting, non-diffractive beams, top-hat shaping, U-shaped beams, and triangular beams, are discussed for improving process speed, precision, and integration of ultra-short pulse lasers. The paper also addresses the challenges of fibering the laser for industrial integration and how beam shaping overcomes these hurdles. In conclusion, beam shaping proves to be a valuable tool for tackling the unique challenges of micro-processing with ultra-short pulse lasers, enhancing process speed, precision, and integration into various applications.
