Laser Micro-Machining Technique Developed30 August 2012
Laser micro-machining is one of the technique used for a wide range of precise machining applications and now a new technique has been developed that can produce laser beams with unusual modes of electric field. The new technique is developed by scientists at University of Liverpool and the research findings have been published in the Journal of Optics.
The new technique could find broad ranges of applications and can have major impacts by increasing the process efficiency and use of different modes of polarization or electric fields. The applications such as producing radial and azimuthal polarization modes have been successfully demonstrated by researchers at Liverpool School of Engineering by using Hamamatsu Spatial Light Modulator.
Research team used a 100 femtosecond (fs) pulse laser source & a spatial light modulator with a wave plate for demonstrating the new technique. The new mode of polarization has provided much better quality of processing speed and further the radially polarized team has increased the machining speed due to higher absorption of radial polarization, which increased the coupling of laser energy during machining.
