摘要

研究表明，硒化物玻璃中Tb3+向Nd3+非辐射能量转移的敏化方案适用于泵浦中红外Nd3+离子激光器。在液氮温度下，Nd3+离子的受激发射对应于新的激光跃迁4I1/2–4I9/2。使用腔内CaF2棱镜，激光器的可调谐范围从5.56μm到6.01μm。已获得高达16mJ的输出能量。

Application of non-radiative energy transfer from Tb3+ to Nd3+ for pumping a 6 μm solid-state laser

It has been shown that the sensitization scheme involving non-radiative energy transfer from Tb³⁺ to Nd³⁺ in selenide glass is suitable for pumping a mid-infrared Nd³⁺ ion laser. Stimulated emission corresponding to a novel laser transition ⁴I_11/2–⁴I_9/2 of Nd³⁺ ions was demonstrated at liquid nitrogen temperature. Using an intracavity CaF₂ prism, the laser was tunable from 5.56 to 6.01 μm. Output energy up to 16 mJ has been obtained.

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
