【摘要】：由于2μm～3μm波段激光在軍事國防、環(huán)境監(jiān)測(cè)、醫(yī)學(xué)治療等領(lǐng)域有巨大的應(yīng)用前景,國內(nèi)外科研機(jī)構(gòu)都已開展相應(yīng)研究。現(xiàn)已商用的ZBLAN光纖在2μm～3μm波段有良好的激光輸出。但是氟化物自身存在著物化性能差、制備條件苛刻等問題。氟碲酸鹽玻璃是在氟化物玻璃基礎(chǔ)上添加適量Te02得到的。這類玻璃是一種結(jié)合了氟化物玻璃良好的光學(xué)特性和碲酸鹽玻璃良好的物化特性,并且成玻璃范圍大,成分可調(diào),從而有望獲得性能良好的2μm～3μm激光輸出的材料。本論文研究內(nèi)容主要為：1.不同Te02含量對(duì)氟碲酸鹽玻璃物化性能、結(jié)構(gòu)特性和透過光譜性能的影響。2.研究了不同Te02含量對(duì)摻Er3+氟碲酸鹽玻璃物化性能、結(jié)構(gòu)特性和光譜性能的影響,獲得了具有良好2μm～3μm熒光特性的玻璃基質(zhì)。3.研究了Er3+摻雜熒光光譜特性和Er3+/Er3+能量傳遞機(jī)理。研究了Ho3+/Yb3+和Ho3+/Tm3+共摻氟碲酸鹽玻璃的光譜性能,并獲得了具有良好的2μm～3μm熒光特性。
[Abstract]:Since 2 渭 m ~ 3 渭 m-band laser has great application prospects in military defense, environmental monitoring, medical treatment and other fields, research institutions at home and abroad have carried out corresponding research. The commercial ZBLAN fiber has good laser output in 2 渭 m ~ 3 渭 m band. However, fluoride itself has some problems such as poor physical and chemical properties, harsh preparation conditions and so on. Fluoride tellurite glass is obtained by adding appropriate amount of Te02 to fluoride glass. This kind of glass is a kind of material which combines good optical properties of fluoride glass and good physical and chemical properties of tellurite glass, and has a wide glass-forming range and adjustable composition, so it is expected to obtain a good laser output material of 2 渭 m ~ 3 渭 m. The main contents of this thesis are as follows: 1. Effects of different Te02 contents on physical and chemical properties, structural properties and transmittance spectra of fluorotellurite glasses. The effects of different Te02 contents on the physical and chemical properties, structural properties and spectral properties of Er3 doped fluorotellurite glasses were studied. The glass substrates with good fluorescence characteristics of 2 渭 m ~ 3 渭 m were obtained. 3. The glass substrates with good fluorescence characteristics of 2 渭 m ~ 3 渭 m were obtained. The fluorescence spectra of Er3 doping and the energy transfer mechanism of Er3 / Er3 were studied. The spectroscopic properties of Ho3 / Yb3 and Ho3 / Tm3 co-doped fluorotellurate glasses were studied, and good fluorescence characteristics of 2 渭 m ~ 3 渭 m were obtained.
