我们报告的光谱和散装激光器的性能特性Tm 3+掺杂碲酸盐玻璃作为增益介质工作在1.9 μ m左右时。研究了TZN和TZNG两种玻璃基质，并对它们的性能进行了比较。在每种情况下，得到了良好的特征连续激光器的性能，这已涉及到详细的光谱测量的重要激光跃迁参数的1900 nm左右时，在793 nm泵浦。TZNG样品获得的最大输出功率为124 mW，相关斜率效率为28%，调谐范围为135 nm。效率和损耗分析得出Tm3+：TZN的计算最大可达效率为48%，而TZNG主体为28%。(C)2008年美国光学学会
We report spectroscopic and bulk laser performance characteristics for Tm3+-doped tellurite glasses when used as gain media operating around 1.9 mu m. Two glass hosts studied are TZN and TZNG and their performances have been compared. In each case, well-characterized cw laser performance was obtained and this has been related to detailed spectroscopic measurements of the important lasing parameters of the laser transitions around 1900 nm when pumped at 793 nm. The maximum output power achieved was 124 mW from the TZNG sample with an associated slope efficiency of 28 % with a tuning range of 135 nm. Efficiency and loss analyses yielded a calculated maximum attainable efficiency of 48 % in Tm3+: TZN compared to 28 % for the TZNG host. (C) 2008 Optical Society of America
