Ionization degree measurement in the gain medium of a hydrocarbon-free rubidium vapor laser operating in pulsed and CW modes

X Zhao, Z Yang, W Hua, H Wang, X Xu - Optics express, 2017 - opg.optica.org
Although the diode pumped alkali laser (DPAL) works in a three-level scheme, higher
energy-state excitation and ionization processes exist during operation, which may lead to …

Collisional excitation transfer and quenching in -methane mixtures

MA Gearba, JH Wells, PH Rich, JM Wesemann… - Physical Review A, 2019 - APS
We have examined fine-structure mixing between the rubidium 5 P 3/2 2 and 5 P 1/2 2 states
along with quenching of these states due to collisions with methane gas. Measurements are …

Role of adiabaticity in controlling alkali-metal fine-structure mixing induced by rare gases

Temperature Dependent Rubidium-Helium Line Shapes and Fine Structure Mixing Rates

WS Miller - 2015 - scholar.afit.edu
Abstract Diode Pumped Alkali Lasers (DPALs) are a new type of laser that uses alkali metal
vapor as a gain medium and a buffer gas to control the line shape and kinetics. While these …
