新型蓝-绿波段激光染料的研究

Study of Novel Lasing Dyes in Blue green Region

合成了四种蓝－绿波段的激光染料，测定了它们的光谱数据、激光调谐范围和激光转换效率。用倍频ＹＡＧ激光器泵浦，其中两个含三氟甲基的染料具有较宽的调谐范围：４７０～５４０ｎｍ和４５６～５１６ｎｍ；较高的激光效率：４１．４％和２６．６％，以及稳定的光化学性能。具有实用价值。

Four lasing dyes in the blue green region were synthesised.The spectra and lasing properties of these dyes were determined. Two of them containing trifluoromethyl group have wide laser turning ranges (470～540 nm and 456～516 nm) and show high lasing efficiencies (41.4% and 26.6%) in a YAG laser pumped experiment.
