Laser Ablation

Laser ablation has a wide variety of applications - from re-shaping the cornea of the eye to correct vision and micro-machining electronic devices, to detection of minute contaminants on catalysts. This book is the proceedings of one of the first workshops held on this topic.

Lasers can readily remove very thin layers from small areasof a material and can thus be used both to control thestructure of the surface and to determine its composition.Laser ablation thus has a wide variety of applications -from re-shaping the cornea of the eye to correct vision andmicro-machining electronic devices, to detection of minutecontaminants on catalysts. This book is the proceedings ofone ofthe first workshops held on this topic.
