Abstract[English]
The present disclosure generally relates to the field of laser based medical devices. Particularly, but not exclusively, the present disclosure relates to an apparatus and method for enhancing laser beam efficacy in a liquid medium. In many embodiments, laser pulses are modulated based on bubble dynamics to improve energy delivery to a target. A variety of exemplary pulse modulation scheme are described including modulating pulse power down during expansion of an index bubble and modulating pulse power up during collapse of the index bubble.[French]
La présente divulgation concerne de manière générale le domaine du recyclage des dispositifs médicaux basés sur un laser. En particulier, mais pas exclusivement, la présente invention concerne un appareil et un procédé pour améliorer l'efficacité d'un faisceau laser dans un milieu liquide. Dans de nombreux modes de réalisation, les impulsions laser sont modulées sur la base de la dynamique des bulles pour améliorer l'apport d'énergie à une cible. Divers schémas de modulation d'impulsion donnés à titre d'exemple sont décrits, comprenant la modulation de la puissance d'impulsion vers le bas pendant l'expansion d'une bulle d'indice et la modulation de la puissance d'impulsion vers le haut pendant l'effondrement de la bulle d'indice.
