Laser ablation
With the support of ACAP Infrastructure Funding we have installed a brand new Pharos laser in the photovoltaic laser laboratory at ANU. With a pulse duration adjustable over a wide range from femto- to picoseconds, three selectable wavelengths, motorized attenuators and lambda/2 waveplates, it is a quite slick setup offering a broad range of applications in laser ablation and processing.
