Melle Hernández, Sonia ; Gómez Calderón, Óscar ; Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando ; Egatz-Gómez, Ana | OSA Publishing | 2012The homogeneous linewidth of the transition I15/24?I13/24 in highly doped erbium fibers and its dependence with temperature in the range from 10 to 50 K are experimentally characterized using spectral hole burning. The homogeneous linewidth depe[...]![]()

Gonzalo Fonrodona, Isabel ; Antón Revilla, Miguel Ángel ; Carreño Sánchez, Fernando ; Gómez Calderón, Óscar | American Physical Society | 2005-09-13The squeezing spectrum of the fluorescent light is investigated for a laser-driven three-level atom of the Lambda configuration when quantum interference of the decay channels is accounted for. We show that when the two atomic transitions contri[...]![]()

Carreño Sánchez, Fernando ; Gómez Calderón, Óscar ; Antón Revilla, Miguel Ángel ; Gonzalo Fonrodona, Isabel | American Physical Society | 2005-06-15We study the dispersion and absorption spectra of a weak probe in a Delta-type three-level atomic system with closely ground sublevels driven by a strong field and damped by a broadband squeezed vacuum. We analyze the interplay between the spont[...]![]()

Transverse effects in the laser threshold, originated by electronic-vibrational coupling in the active centers, are analyzed theoretically by means of the semiclassical two-level Maxwell-Bloch equations. A single longitudinal mode is considered.[...]![]()

S. ; Jacinto, Carlos ; Rosal, Blanca, del ; Kar, Ajoy K. ; Rubio Retama, Jorge ; Jaque García, Daniel | Nature Publishing Group | 2020-06-10Optical probes operating in the second near-infrared window (NIR-II, 1,000-1,700?nm), where tissues are highly transparent, have expanded the applicability of fluorescence in the biomedical field. NIR-II fluorescence enables deep-tissue imaging [...]
