“…Thus, the crystallization of the b-BBO phase on the surface of the BBS sample was evaluated as a function of the laser power, irradiation time and surface condition. These results are compared to that obtained previously with the 40BaO-45B 2 O 3 -15TiO 2 glass composition (dubbed BBT) [16].…”

“…A continuous or pulsed CO 2 irradiation laser has been used to modify or promote crystallization on the surface of oxide or glassy metal samples [3,[14][15][16][17], but, to the best of our knowledge, the literature contains relatively few studies concerning crystallization on the surface of glass materials using this laser source [3,[15][16][17]. Due to the nature of its wavelength (k = 10.6 lm) and the absorption of oxide glasses, CO 2 laser irradiation acts directly on photon-phonon coupling, simultaneously heating all the atoms in the exposed volume of a sample [16].…”

“…Due to the nature of its wavelength (k = 10.6 lm) and the absorption of oxide glasses, CO 2 laser irradiation acts directly on photon-phonon coupling, simultaneously heating all the atoms in the exposed volume of a sample [16]. The crystallization mechanism on this case has been attributed mainly to a thermal effect [3,[15][16][17].…”

“…Recently, we developed a detailed study of the crystallization and permanent modification of the surface of a 40BaO-45B 2 O 3 -15TiO 2 glass composition using a CW CO 2 laser light [16]. We observed that the geometry of permanent deformation induced by irradiation depends mainly on the laser power and the sample's surface condition.…”

“…We chose this composition because it has been shown that the b-BBO phase can be efficiently obtained from this glass composition when heat-treated in an electrical furnace [18]. Previous works have also shown that by using the laser irradiation process, the crystallization of b-BBO phase on the surface of glass samples is easily achieved if micrometer sized particles of the b-BBO phase are set onto the glass surface before irradiation [10,16]. Thus, the crystallization of the b-BBO phase on the surface of the BBS sample was evaluated as a function of the laser power, irradiation time and surface condition.…”

[Publié en ligne le 09/03/2013]International audienceOnline UV/visible extinction measurement have been achieved during nanosecond Nd:YAG laser irradiation at 532 nm of a silver-exchanged silicate glass after each shot. We have explained the evolution of the integrated spectral evolution with the help of a few observed spots after the laser/glass interaction and completed them by optical and surface measurements. This optical method allows to in situ follow silver ions precipitation in nanoparticles (NPs) and the consequently surface plasmon resonance evolution (SPR). In this study, we focus on the interest of this method for one silver-exchanged soda-lime glass by direct observation of the sample surface. Scanning electron microscopy measurement and optical microscopy were used to identify the various ablation mechanisms. Profilometry was used to evaluate the material distribution and the surface roughness evolution (Rms parameter). Thus, we explain the silver NPs effect on glass matrix at various micrometric scales according to the deposited fluence and silver concentration

This paper reports the recent progress in the laser patterning of optical active crystals such as BaAlBO 3 F 2 and ␤-BaB 2 O 4 in glasses. In the laser-induced crystallization using continuous-wave lasers such as Yb:YVO 4 fiber lasers (wavelength: 1080 nm), a steep temperature gradient is created in the laserirradiated region, and highly oriented crystal lines are patterned at the glass surface. The quality and orientation of crystals patterned are characterized from the azimuthal dependence of second harmonic intensities, polarized micro-Raman scattering spectra, and transmission electron microscope observations. Two-dimensional planar crystals with high orientations are patterned by applying laser irradiations with large overlapping. The patterning of crystals in the inside of glass fibers is also possible by moving gradually laser focal point from the surface into the inside. The progress in the crystal patterning with desired morphologies and high orientations provides a high potential for optical active device applications.
