Abstract

In order to obtain a high laser efficiency from Xe pumped Nd laser systems, a novel cavity filter glass doped with Eu³⁺ and Sm³⁺ was investigated using a phosphate host. Sm³⁺, which served to inhibit ASE also was found to strongly transfer its energy to the Eu³⁺. The Eu³⁺ emits an efficient red emission from the ⁵D₀ yields ⁷F₁ transition which is located exactly at the Nd³⁺ absorption band and therein radiatively sensitizes the Nd laser emission. The energy transfer and back transfer of these two rare-earth ions in phosphate will be discussed. This doubly-doped phosphate glass cavity samples produced an increase in output power by 50 percent over undoped filters in a Xe pumped pulsed Nd:glass laser system.
