Experimental studies on the development and propagation of shock waves created by the interaction of short Nd:YAG laser pulses with a titanium target

Abstract

The formation and propagation of shock waves created by the interaction of high powered Nd:YAG laser pulses with a titanium target are photographed and analyzed. The titanium target is located at the distal end of a probe, similar to an irrigation/aspiration probe used in cataract surgery, and the Nd:YAG laser is delivered by a cladded 300 microns quartz fiber. This device, and the results of this study, are being applied to develop a device for fragmenting nuclear material for cataract extraction.
