A pulsed L L F : F ~ centers laser coaxially pumped by a nitrogenlaser-pumped dye laser operating at 460nm is reported.The laser output extended from 510nm to 580nm using an L I F crystal and a single pump wavelength.Eight hundred watts peak p m e r with a pulse duration of 4ns is obtained at room temperature.
In this paper, we describe systematically some experimental results of the optical characters of the creaion of F3+ centers in LiF crystal by electron bombardment under different conditions. The relative density between F3+ and F2 centers are analysed from fluorescence spectra. The experimental results show that irradiation temperature plays an important role in the creation of F3+ and F2 centers and affects the relative density of F3+ and F2 centers. The main results are as follows: (1) Irradiation at liquid nitrogen temperature and then warming up to room temperature in the dark can create F3+ canters with high density, which can be seen from the fluoreseence spectra, as fluorescence of F3+ centers centered at 530 nm is much stronger than that of F2 center (670 nm) and fewer N centers and R centers are presented in absortion spectra. (2) From dynamic fluorescence spectra, it can be shown that in the samples irradiated at liquid nitrogen temperature, the density of F3+ centers increase rapidly when F2+ centers decays. But in the samples irradiated at room temperature the growth of F3+ and F2 centers are approximatly with the came rate. (3) We observd the band width and double pike structure of the fluorescence excitation spectra of F3+ and F2 centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
