中文摘要 | Bi掺杂的玻璃能够发射覆盖900到1650nm波长范围内的超宽带红外发光,荧光最大半高宽约3 OOnm,荧光寿命约为几百微秒。Bi掺杂玻璃的独特超宽带光学性能预示着它很有可能成功克服目前稀土离子掺杂光纤放大器的放大带宽不足和拉曼光纤放大器的多波长激发的缺点,并有希望成为全新一代的超宽带光放大材料。虽然Bi掺杂玻璃的荧光性能得到了大量研究,但是,迄今为止,Bi掺杂材料的红外发光机理仍不明确,光放大和激光输出的报道集中在Bi掺杂石英玻璃上,关于多组分玻璃的光放大和激光输出报道较少。 |
英文摘要 | Recent studies show that the ultrabroadband luminescent spectra of Bi-doped glasses covers the wavelength region of 900-1650nm, the Full Width at Half Maximum (FWHM) and its luminescent lifetime are above 300nm and several hundred microseconds, respectively. Because of their unique luminescent Bi-doped Although glasses are promising candidate materials for broadband optical properties, amplifiers. lots of investigations have been focused on Bi-doped glasses, the mechanism of Bi-related near-infrared (NIR) luminescence is still in controversy. Although many studies about optical amplification and laser operation were concentrated on Bi-doped silica glass and fiber, less research on Bi-doped multi-component glass was repoued. |
