Abstract
Cultural Heritage has many analytical and treatment needs
both in the field of conservation than in restoration. The laser therefore found a ready-made
place in this area. We find first the different application of laser cleaning. The LRMH was the
initiative of creating the first field prototype used in the field for cleaning stone in
particular. A tour of the Cathedral of France to test this method had been achieved in the early
90s. Then, many have phenomenological and physical studies were conducted to understand the
mechanisms involved during the cleaning action. In analytical technology, LIBS (Laser Induced
Breakdown Spectroscopy) is used for in situ identification of pigments, salts, metals or other
materials. This laser technique present a lot of advantages: portability, analysis of light
elements, stratigraphic analysis capability ...The LRMH was the first laboratory depending from a
ministry of culture to get the technology and to apply it systematically in situ (Saint-Savin sur
Gartemps abbey...). In addition, more recently, a methodology for converting pigments by
continuous laser was developed in the laboratory, thus extending the scope of the use of laser.
We review these techniques and their application based on studies that occur in our laboratory.
