Compact Laser Sources for Third Harmonic Generation and Multi- photon absorption microscopy

摘要

The general utility of two compact femtosecond laser sources for Third Harmonic Generation (THG) and Multiphoton absorption microscopy is demonstrated. The effect of aberrations due to a dielectric interface on THG microscopy is investigated both from a theoretical and experimental point of view. The significance of these aberration issues in third order nonlinear optical susceptibility (x~(3)) measurements using THG microscopy is discussed.
