新型吡咯甲川-BF_2化合物的光谱和激光性能研究

Spectral and Laser Performance of Novel Pyrromethene-BF_2 Compounds

合成了 6个最大吸收波长位于 5 17nm～ 5 2 4nm的新型吡咯甲川 BF2 化合物 ,测量了它们在无水乙醇溶液中的电子吸收光谱。测试结果表明 ,6个化合物的激光性能全部优于若丹明 6G。

Six novel pyrromethene BF 2 compounds, with peak absorption wavelength in the range of 517 nm～524 nm, were synthesized. The electronic absorption spectra were measured in their solution of absolute ethanol. Pumped with a frequency doubled pulsed Nd 3+ ∶YAG laser at 532 nm, they can lase more efficiently than rhodamine 6G and show wide tunability.
