laser micromaching encables precise control of the geometry by adjusting the speed and power of the laser beam, and is generally very rapid only a few seconds.
Laser micromachining is a versatile process and is used widely for machining plastic, glass, metal as well as preparing thin foils. The process comprises different mechanisms like cutting, drilling, marking, turning, threading, etc.
The recent advances in laser micromachining includes its utilization for controlled fracture in fine items, enhancement in drilling high aspect ratio micro holes on the basis of helical drilling where, material is removed by helical passes by dividing the total machining length into several single passes, trepanning where laser spot moving in circular fashion and polarization control by changing linear polarization to circular is required. Also, polarization control can aid the helical drilling to fabricate high quality, precise and high aspect ratio micro holes.
