We have obtained the absolute absorption cross-sections of Yb-doped phosphate QX laser glass at 300 K from 800-1100 nm, and generated the emission cross-sections via the standard method of reciprocity. By generating nine detailed high-confidence fitt

In this paper, the temperature distribution is derived analytically within a fiber laser end pumped by a top-hat beam subjected to an external convection at the cladding surface. The temperature distribution is obtained through considering the radial

This paper is the first of a two-part manuscript whose overall objective is to present a unified mathematical kinetics model of four-level laser systems solidly anchored to known physics, optics, and materials considerations, but ultimately viewed fr

We develop a detailed kinetics model for Yb:YAG operating at any temperature and derive expressions for the heat, fluorescence, and lasing power densities and fractions, using a theoretical framework that includes conservation of ions (and power), sa

Saturation effects in solid-state laser materials are important to accurately model and optimize the performance of laser devices. In this paper, we present analytical and numerical results describing the absorption in continuous wave solid-state las

HIV- and AIDS-related stigma has been reported to be a major factor contributing to the spread of HIV. In this study, the authors explore the meaning of stigma and its impact on HIV and AIDS in South African families and health care centers. They con
