Recently published research carried out using the DiPOLE laser, in collaboration with colleagues from Coventry University, Loughborough University, and the University of Malta, has shown that laser shock peening can improve the toughness of silicon nitride ceramics. These ceramics are used in applications such as cutting tools, hip replacements, bullet proof vests, rocket nozzles, and components for the space industry. The benefits of greater durability that laser shock peening provides are potentially significant.

Laser shock peening of ceramics is an underdeveloped process; the results of this novel investigation are important as they provide an understanding of laser material interactions in laser peening of silicon nitride ceramics, which paves the way for further research.

The DiPOLE amplifier technology allows for the temporal pulse shape and width to be easily modified to suit these experiments, and with its automatic beam alignment and adaptive optic systems ensures that a high level of beam quality is maintained.
