Ruby laser beam interaction with ceramic and copper artifacts

Copper and Aluminum in Cultural Heritage: The Analysis of Damage Threshold of Material in Interaction With Ruby Laser

“…Fewer projects dealt with testing the effects of interaction of ruby laser light and objects of cultural heritage. The largest part of the metal has a low absorption coefficient of visible spectrum, while the reflection coefficient varies from 30 to 95%, depending on sediments and the quality of surface treatment [18,19].…”

Studies of the Iranian medieval ceramics surface modified by pulsed tea CO2 and Nd:YAG lasers

“…In general, pulsed CO 2 and Nd:YAG lasers are extensively used for diagnostics and processing (cleaning, cutting, drilling, milling or marking) of ceramics and many other different materials [25][26][27]. Due to the thermal nature of interaction, chemical decomposition, thermal stresses and microcracking, amorphous material phase formation caused by melting and rapid resolidification, sometimes cannot be avoided during the use of these lasers.…”

“…Nevertheless, apart from these shortcomings, the advantages of laser application in cleaning ancient ceramics surface encrustations are evident [1,2,10,[25][26][27][28][29][30].…”

Laser Ablation Cleaning Effects on Thermoluminescence Dating Technique

“…In fact, the mechanical removal of encrustation by mechanical instruments and abrasive particles can scratch the surface artifacts (Nikolov et al, 2004). In recent years, scientific investigation has led to the study of new technologies applied to cultural heritage (Ristic et al, 2010).…”

“…Lasers are widely used in various fields of science, technology, art, and cultural heritage protection and optical methods that use lasers as light sources are applied in different diagnostics technique (Ristic et al, 2010). In particular, laser cleaning technique, based on the removing of the impurities through the process of laser ablation, LA, is frequently used in restoration of stone and ceramic artifact (Barberio et al, 2013;Salimbeni et al, 2000;Lanterna et al, 2000).…”
