Abstract
παρούσα εφεύρεση αναφέρεται σε μια μέθοδο και ένα σύστημα για τον καθαρισμό επιφανειών από πάσης φύσεως επιφανειακές επικαθίσεις, με την σύγχρονη χρήση της θεμελιώδους και μίας αμρονικής συχνότητας ενός laser βραχέως παλμού (της τάξης των 1 έως 40ns) σε χρονική και χωρική επικάλυψη παλμοσειρών και σε διαφορετικές μεταξύ τους αναλογίες πυκνοτήτων ενέργειας. Η παρούσα εφεύρεση λύνει ένα πρόβλημα μείζονος σημασίας που αναφέρεται στον καθαρισμό πέτρινων γλυπτών επιφανειών ιστορικής ή/και καλλιτεχνικής αξίας χωρίς την παραμικρή αλλοίωση των υποκείμενων αυθεντικών επιφανειών. Η εφεύρεση μπορεί να εφαρμοσθεί και σε άλλα υλικά όπως προσόψεις κτηρίων, μεταλλικές επιφάνειες, γυαλί, χαρτί, ξύλο κλπ. καθώς και σε διάφορες άλλες εφαρμογές βιομηχανικού ή ιατρικού ενδιαφέροντος, όπως παραδείγματος χάριν η αφαίρεση ραδιενεργών καταλοίπων από πάσης φύσεως επιφάνειες ή η αφάιρεση επικαθίσεων από πάσης φύσεως ζωικούς ιστούς. Η επιτυχία της μεθόδου βασίζεται στη σύγχρονη λειτουργία δυο διακριτών μηχανισμών αφαίρεσης επιφανειακών επικαθίσεων μέσω της σύγχρονης χρήσης παλμών laser δυο διαφορετικών μηκών κύματος. Το προτεινόμενο σύστημα βασίζεται στην χωρική και χρονική σύμπτωση της παραγόμενης αρμονικής ακτινοβολίας με τη θεμελιώδη ακτινοβολία από την οποία παράγεται, καθώς και στη μεταβολή της ενέργειας των δύο επί μέρους ακτινοβολιών χωριστά. ΰ
