Pump-Probe Laser Imaging to Improve the Arts

Facebook X LinkedIn Email
RALEIGH, N.C., July 16, 2013 — A pump-probe laser technique designed to diagnose melanoma has now been applied to art, uncovering paint pigments and layering techniques noninvasively to provide historical insight into works of art. The interplay of art and science is subtle but important, and now North Carolina Museum of Art (NCMA) conservators and Duke University scientists are collaborating to better recognize the paint and other materials used in the creation of the 14th-century “Crucifixion” by Puccio Capanna using a nondestructive pump-probe laser and an Er:YAG laser cleaning tool. The knowledge...Read full article

    er:yag laser
    An Er:YAG laser is a type of solid-state laser that uses a crystal made of erbium-doped yttrium aluminum garnet (Er:Y3Al5O12) as the gain medium. The erbium (Er) ions are introduced into the crystal lattice of yttrium aluminum garnet (YAG) to provide the lasing action. The Er:YAG laser is known for its ability to emit laser light at a specific wavelength in the infrared region, making it particularly well-suited for various medical and dental applications.
