IL LASER A FIRENZE
Leonardo Masotti
Congresso Società Italiana di FisicaBologna 24 Settembre 2010
Premesse sul Laser a Firenze1941 Già scoperto il principio di interferenza inversa di G.
Toraldo1955-1958 Collaborazione di G. Toraldo con l’Istituto Nazionale di
Ottica e con il Centro Microonde del CNR.Tra i tanti risultati importanti, citiamo:-la previsione e dimostrazione sperimentale dell'esistenza delle onde evanescenti; e specialmente-lo studio del campo elettromagnetico di un elettrone relativistico, rappresentato in termini di onde evanescenti, di particolare valore per la raffinata analisi fisico-matematica e per le interessanti applicazioni alla classe degli effetti quasi-Cerenkhov;-il settore delle lenti geodetiche, ideate per le microonde e trasportate poi nel campo dell'ottica integrata;-gli studi sulle antenne.

Laser medical applicationsMAIN APPLICATIONS
Dentistry: little amount of anaesthetic, no drill noise and vibration foradvanced therapeutic solutions to maximize clinical advantage withoptimal post-operative prognoses and results
Surgery and plastic surgery: laser is a sterilized bistoury, lasersears so the healing is rapid with an aesthetic perfect result, thedevelopment of laser technology and the ever-increasingunderstanding of laser-tissue interaction has led to widespread useof lasers in the operating room
Sport medicine: in functional re-education and sports relatedindications optimizing performance and recovery time of muscularfunctions, salutary biostimulation without secondary effects
Laser medical applicationsMAIN APPLICATIONS
Aesthetic medicine and surgery: selective interaction for hairremoval with, controlled laser energy delivery: body care, skinrejuvenation, tattoo removal, angioma removal
Gynaecology: no-contact operations in laparoscopic andcolposcopic surgery ensuring rapid post-operative recovery
Endoscopic surgery: laser energy, transported through very thinand flexible optical fibers, allows for inducing controlled and localizedhyperthermia in less accessible areas
ENT surgery: for the micro-surgical endoscopic treatment of severallaringeal and ear pathologies (myringotomia-otosclerosis)

La prima mappa tematica mette in evidenza la presenza di Chl e uno specifico pixel corrisponde alla fluorescenza relativa a una pianta superiore. Infatti un anno dopo si è verificato che adesso questa pianta era visibile. Le altre mappe quantificano la fluorescenza dovuta all’ Chl per gli altri due cluster.
