Journal ArticleDOI
Random fiber laser.
Christiano J. S. de Matos,Leonardo de S. Menezes,Antonio M. Brito-Silva,M.A. Martínez Gámez,Anderson S. L. Gomes,Cid B. de Araújo +5 more
TL;DR: A comparison with similar systems in bulk format shows that the random fiber laser presents an efficiency that is at least 2 orders of magnitude higher than the classical random laser system operating in the incoherent feedback regime.
Journal ArticleDOI
Optical properties of Dy3+-doped P2O5 - K2O - MgO/MgF2 - Al2O3 glasses
K. Upendra Kumar,K. Upendra Kumar,Ch. Srinivasa Rao,C.K. Jayasankar,S. Surendra Babu,J. L. Lucio,Miguel A. Vallejo H,M.A. Martínez Gámez +7 more
TL;DR: In this article, optical and fluorescence properties of Dy2O3-doped P2O5+K2O+MgO+Al 2O3 glasses have been investigated at room temperature.
Journal ArticleDOI
Multi-wavelength visible up-converted luminescence in novel heavily doped Ytterbium-Holmium silica fiber under low-power IR diode pumping
Alexander V. Kir'yanov,Vladimir P. Minkovich,Yu. O. Barmenkov,M.A. Martínez Gámez,Alejandro Martinez-Rios +4 more
TL;DR: In this article, a silica fiber with ytterbium (Yb3+) and holmium (Ho3+) for the use as a potentially lasing and amplifying fiber-optic material is reported, and luminescent properties of the fiber are studied in the visible and near-IR spectral ranges under the low power IR diode pumping.
Journal ArticleDOI
Diode-pumped self-Q-switched erbium-doped all-fibre laser
S.G. Cruz Vicente,M.A. Martínez Gámez,Alexander V. Kir'yanov,Yu. O. Barmenkov,Miguel V. Andrés +4 more
TL;DR: In this paper, a diode-pumped self-Q-switched erbium-doped fiber laser was developed and studied, and the most probable mechanism of passive Q-switching of the laser cavity is absorption from the excited state of the ionized material, resulting in a thermally induced nonlinear change in the refractive index in the fiber.
Journal ArticleDOI
The luminescent properties of Er3+–Yb3+-doped fluorophosphate fiber glass preforms at high temperatures
TL;DR: In this paper, the optical properties of fluorophosphate Er3+−Yb3+ fiber preforms with different concentrations of ErF3 and YbF3 were investigated in the temperature interval 25-300°C.
