Abstract: An additive, preferably in the form of metal nanoparticles or nanodomains, greatly improves a laser-based method and system for inducing optical breakdown. The use of ultrashort laser pulses to induce laser-induced breakdown (LIB) in metal nanoparticles or nanocomposites makes it possible to reduce significantly the threshold laser energy required for LIB. Such nanoscale (submicron) metallic particles allows one to control the LIB process. The nanoparticles can be synthesized so as to target specific biological structures or tissues (dendrimer nanoparticles are one system for which this has been demonstrated). This opens up the possibility of performing LIB for targeted cancer treatment or microsurgery.

Abstract: Selective photocoagulation of particular cells, tissue or portion of tissue can be aided by monitoring microcavitation within the material exposed to electromagnetic radiation (12). The information gained by the detection of microcavitation events can be used to modulate the intensity of the radiation (12) to prevent significant thermal energy transmission and mechanical damage to cells, tissues or portions of tissues which are not directly exposed, but prone to thermal damage by such energy transmission.

The inventive methods can help prevent the formation of blind spots that can be associated with laser eye surgery. Other fields of laser surgery can also be readily adapted to the methods described herein.
