We report the performance of two new laser dyes, Pyrromethene 580 and 597, in a 10-Hz, Nd:YAG-pumped dye-laser system. These dyes demonstrate broader and more efficient tuning curves compared with those of Rhodamine 590 and 610. Pyrromethene 580 and 597 provide peak conversion efficiencies of 38% at 552 nm and 32% at 571 nm, respectively. Moreover, these new dyes provide conversion efficiencies of 31% near 572.5 nm, a wavelength used for fluorescence studies of NO. This enhanced efficiency should improve the signal-to-noise ratio in linear fluorescence [NO] measurements.
我们报告了两种新型激光染料——吡咯甲川580和597在10赫兹、钕:钇铝石榴石泵浦染料激光系统中的性能。与若丹明590和610相比，这些染料展现出更宽且更高效的调谐曲线。吡咯甲川580和597分别在552纳米处提供38%的峰值转换效率，在571纳米处提供32%的峰值转换效率。此外，这些新型染料在572.5纳米附近提供31%的转换效率，该波长用于一氧化氮的荧光研究。这种提高的效率应会改善线性荧光[一氧化氮]测量中的信噪比。
