Ultra-fast Laser Allows Efficient, Accessible Nanoscale Machining

University of Michigan researchers have explained how a femtosecond pulsed laser enables extraordinarily precise nanomachining. One of the biggest problems that exists when dealing with nanotechnology is having a way to build and maintain the devices. The ultra-short pulsed laser used at a very high intensity make it possible to cut away amounts small as 20 nanometers and it also has the ability to do 3-D machining. This could provide a great step into nanotechnology and effectively pursuing its field.
