Course objectives

Main goal of the course is to inform students students with applications of optical methods and lasers in the protection of cultural heritage.

Syllabus

1.Principle of laser, prperties of lasr irradiation, laser types used in the cultural heritage protection; interaction of laser beam with material.
2.Plasma induced by laser, supersound. Diagnostics of laser plasma.
3.Chemical reactions (pyrolysis, polymerization, cluster formation, … ) and degradation of materials by effect of laser.
4.LIBS a LIF, interference (spectrak and non-spectral), application of methods.
5.Checking of cleaning process, deposition using LIBS, acoustic signal etc.v 6.Laser desorption of organic molecules (MALDI), laser ablation (with ICP), laser micropyrolysis (with GC-MS).
7.Ablation in liquids, laser plasma in liquids, cavitation caused by laser.
8.LIBS of solids in liquid media (analysis of artefacts under water) and analysis of suspensions and solutions. 9.Removing of corrosion products and undesirable surface preparations.
10.Laser deposition of anticorrosive and protecting layers.Formation of coatings.
11.Chemical synthesis by using laser.
12.Advanced applications: measuring in longer distances by LIBS a LIF (diagnostics of building structures), LIDAR and its application in archaeological prospection.
13.Connection of LIBS with Raman spectroscopy(mikroscopy)- pigment identification.
14.Monitoring of artefact surface quality by interferometry.
15.Exploitation of holographic techniques in survey, documentation and presentation of cultural heritage.
