We report on multimodal coherent anti-Stokes Raman scattering (CARS) imaging with a source composed of a femtosecond fiber laser and a photonic crystal fiber (PCF)-based optical parametric oscillator (FOPO). By switching between two PCFs with different zero dispersion wavelengths, a tunable signal beam from the FOPO covering the range from 840 to 930 nm was produced. By combining the femtosecond fiber laser and the FOPO output, simultaneous CARS imaging of a myelin sheath and two-photon excitation fluorescence imaging of a labeled axons in rat spinal cord have been demonstrated at the speed of 20 μs per pixel.
我们报道了一种多模态相干反斯托克斯拉曼散射(CARS)成像技术,其光源由飞秒光纤激光器和基于光子晶体光纤(PCF)的光学参量振荡器(FOPO)组成。通过在具有不同零色散波长的两根光子晶体光纤之间切换,产生了来自FOPO的可调谐信号光束,其覆盖范围为840至930纳米。通过将飞秒光纤激光器和FOPO输出相结合,已证明在大鼠脊髓中能够以每像素20微秒的速度同时进行髓鞘的CARS成像和标记轴突的双光子激发荧光成像。
