The popularity of lasers in industrial, microelectronic, and medical applications is steadily growing, lasers have established themselves across a wide range of materials processing tasks--among them marking, micro-machining, rapid prototyping, cutting/ routing, microvia drilling and embedded passive trimming. These successes have been facilitated by significant progress in laser technology--higher laser powers, improved beam quality, shorter wavelengths, longer component lifetimes, and advanced focusing and handling systems that move and position the laser focus onto the workpiece.
Compared to conventional technologies, laser-based materials processing offers ...
