多模态非线性光学显微镜是研究复杂生物样品的重要工具。我们提出了一种易于操作的方法来执行相干反斯托克斯拉曼散射(CARS)、双光子荧光(TPF)、二次谐波(SHG)和三次谐波(THG)成像,使用由80 MHz飞秒(fs)激光器、光学参量振荡器(OPO)和用于倍频的PPLN晶体组成的单一激光源。该平台允许对新鲜脊髓组织中富含ch的髓鞘和活细胞中的脂质体进行振动共振CARS成像。展示了新鲜肝组织的多模态非线性光学成像和显微光谱分析。
Multimodal nonlinear optical microscopy is a valuable tool to study complex biological samples. We present an easy-to-operate approach to perform coherent anti-Stokes Raman scattering (CARS), two-photon fluorescence (TPF), second harmonic generation (SHG), and third-harmonic generation (THG) imaging using a single laser source composed of an 80 MHz femtosecond (fs) laser, an optical parametric oscillator (OPO), and a PPLN crystal for frequency doubling. The platform allows vibrationally resonant CARS imaging of CH-rich myelin sheath in fresh spinal tissues and lipid bodies in live cells. Multimodal nonlinear optical imaging and microspectroscopy analysis of fresh liver tissues are demonstrated.
