Abstract研究了三种不同铒离子浓度的Er~(3+), Yb~(3+)共掺杂磷酸盐铒玻璃的光谱性质和激光性质,用2W,974nm半导体激光器作为泵浦源,在Er~(3+)离子浓度为0.12 * 10~(20)/cm~3, 0.48 * 10~(20)/cm~3, 0.88 * 10~(20)/cm~3的Er~(3+), Yb~(3+)共掺杂磷酸盐铒蒲片玻璃中成功地实现了室温连续激光输出。讨论了铒离子掺杂浓度和样品厚度对激光性质的影响。通过比较发现在Yb~(3+)离子浓度相当的条件下(1.5 * 10~(21)/cm~3
Other AbstractLaser properties of Er~(3+), Yb~(3+) co-doped erbium phosphate glass pumped by 974nm, 2W laser diode is reported in this paper. Continuous laser at 1.53mum was obtained at room temperature in this erbium glass. The effect of Er_2O_3 concentration and sample thickness on laser properties was investigated. 0.13wt%, 0.5wt% and 1.0wt% mean Er_2O_3 concentrations and 1mm, 2mm and 3mm sample thickness were used. It is found the laser threshold and slope efficiency is strongly depend on sample thickness and Er~(3+) ion concentrations. At the same Er~(3+) ion concentration, the thicker the sample, the larger the laser threshold. Slope efficiency increases with the Er~(3+) ion concentration at the same sample thickness. At present the best laser properties are realized in glass with 0.5wt% Er_2O_3 concentration and 2mm thickness. In this glass 10.2% slope efficiency, 118mW laser threshold and 43mW maximum laser output were obtained. The laser spectral range is from 1527 to 1533nm. The center laser wavelength is 1530nm.
