Patent number: 9816925Abstract: A method for 3D recording of data on a medium formed from a transparent photosensitive material including at least one dopant. The method includes a first step of calibrating and checking a pulsed light source including calibrating the number of pulses, the level of fluence of each pulse emitted and the rate of the pulses and a step of inscribing an area of the material. The fluence of each pulse emitted, the number of pulses and the rate of the pulses are suitable for irradiating the material in the area so as to form fluorescent clusters stabilized from the dopant while minimizing the modification of the refractive index and the absorption coefficient of the medium in a wavelength range from visible to near infrared.Type: GrantFiled: November 14, 2013Date of Patent: November 14, 2017Assignee: Universite Bordeaux 1Inventors: Lionel Stephane Canioni, Thierry Cardinal, Bruno Bousquet, Arnaud Royon, Matthieu Bellec, Kevin Bourhis, Gautier Papon, Philippe Legros
