研究目的
Discussing the state of the art of neodymium-, erbium-, thulium-, and holmium-doped tellurite glass fiber and microsphere lasers.
研究成果
The review concludes that high-quality rare-earth doped tellurite fibers are promising novel gain elements for lasers and amplifiers in the L-band and in the range of 2 μm and well beyond. Tellurite microsphere lasers are also an attractive platform for developing ultracompact, low threshold, narrow linewidth light sources.
研究不足
The review highlights the technical and application constraints of the experiments, such as the challenges in achieving laser generation at specific wavelengths and the need for high-quality glass samples with low loss and very low content of OH groups.
