The ninth conference on Lasers in the Conservation of Artworks (LACONA) will be held in London from 7–10 September 2011. The meeting is being organised by the Department of Conservation and Scientific Research at the British Museum in collaboration with the Centre for Sustainable Heritage at University College London. The 2011 conference will focus not only on the scientific research behind the use of laser technology but also on the application of lasers to the treatment and analysis of cultural heritage in a way that is directly applicable to conservation practice.
