We report the successful development of an all-solid state laser based on a Czochralski method-grown cerium-doped lithium calcium aluminum fluoride (Ce3+:LiCaAlF6 or Ce:LiCAF) crystal as the gain medium. Results for the broadband, narrow linewidth and sho... see more

In this paper, we present a review of enhancement and wavelength shift of abnormal upconversion green light emission from erbium ions doped in silica with narrow linewidth in the metallic-coated microsphere cavity. Although the phenomenon o... see more

Resumen: Se presentan mediciones de ancho espectral de láseres basados en arreglo de guías de onda tipo grating (Arrayed Waveguide Grating, AWGL), que forman parte de circuitos integrados fotónicos (Photonic Integrated Circuits, PICs, utilizando el método... see more

This work presents the experimental results of narrow gap butt welding of steel plates with large thickness by using the Metal Active Gas (MAG) welding method.The typical defects are accompanied with this process such as the infusion in the side wall and ... see more

BACKGROUND Diabetic retinopathy causes vascular dilatation caused by hypoxia, whereas oxygen tension improvement leads to retinal vessels narrowing. Given that laser photocoagulation aims to increase the oxygen tension in the retina, we hypothesized that ... see more

Resumen Los autores reportan el caso de un paciente femenino de 68 años que cursó con hipotonía y cámara plana en el postoperatorio de un implante Ex-PRESS. Tras resolverse el cuadro se observó obstrucción de la luz de entrada del implante por iris, el c... see more

A Configuration of a second-order distributed feedback dye laser pumped by a nanosecond Nd:YAG laser is setup. The tuning range is narrower than that in the case of the first-order DFDL but lower noise and more stable is obtained. Single picoseconds pulse... see more

We report a design of a cerium-doped lithium calcium hexafluoro aluminumate (Ce:LiCaAlF6_{6}, Ce:LiCAF) laser resonator based on total internal reflection (TIR). This TIR configuration is established by placing the Ce:LiCAF crystal between two calcium flu... see more
