Our finite-difference time-domain (FDTD) simulation results show that the maximum near-field RP-CARS radiation from the two longitudinally orientated nanoparticles is around 1.3 times higher than that from transversely orientated nanoparticles. Our further CARS experiments show that RP-CARS radiation from molecules oriented along the longitudinal direction is approximately 3-fold stronger than that using linearly polarized CARS technique, and the lateral resolution of RP-CARS imaging can be improved by about 10% compared to the linearly polarized CARS imaging. © 2009 SPIE-OSA-IEEE. | Source Title: | Proceedings of SPIE - The International Society for Optical Engineering | URI: | http://scholarbank.nus.edu.sg/handle/10635/74838 | ISBN: | 9780819480361 | ISSN: | 0277786X | DOI: | 10.1117/12.854965 |
