当与若丹明6G染料激光辐射(λ=568.6亳微米)参量混频时,获得氦氖激光红外辐射(λ=1.15微米)在铊蒸气中转换成紫外波段(λ=377.6毫微米)。利用了具有禁戒跃迁6Ρ1/2-7Ρ3/2的泵浦的双光子共振,和转换辐射频率趋近于7Ρ3/2-7S1/2跃迁频率。

Purpose: To evaluate the effectiveness of topical 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT) for the treatment of cutaneous lichen planus (LP). Methods: A total of 17 symptomatic LP lesions in 7 Chinese patients were assessed. ALA cre
基于全球植被的荧光分布,利用GOSAT数据,同步反演了光子光程概率分布密度函数因子和755 nm处的荧光强度,将反演结果与TCCON站点的结果进行了对比。结果表明:对于受植物叶绿素荧光影响较大的Park Falls(45.9°N,90.3°W)站点附近的GOSAT数据,考虑荧光影响前后的二氧化碳(CO2)反演结果的最大偏差为1.6×10 -6;对于受荧光影响稍小的Sodankyla(67.4°N,26.6°E)站点附近的GOSAT数据,最大偏
Increasing interest has been drawn to optical manipulation of metal (plasmonic) nanoparticles due to their unique response on electromagnetic radiation, prompting numerous applications in nanofabrication, photonics, sensing, etc. The familiar point-like l

半导体激光器侧面抽运的内腔倍频激光器是实现高功率、高稳定且低成本连续绿光激光器的有效方式。抗灰迹KTP晶体(GTR-KTP)适用于高功率连续激光倍频,其抗光伤阈值优于普通的KTP晶体,倍频转换效率高。使用该晶体能够避免普通KTP晶体在高功率激光应用中受到“灰迹”效应等严重影响。使用GTR-KTP成功研制了一台高效高功率侧面抽运腔内倍频连续绿光激光器。采用优化的平-凹-平三镜折叠腔结构,掺钕的钇铝石榴石(NdYAG)激光晶体,Ⅱ类相位匹配GTR-KTP晶体内腔倍频,当808 nm抽运功率约为180 W时,得
