Multiphoton microscopy has enabled unprecedented dynamic exploration in living
organisms. A significant challenge in biological research is the dynamic imaging of features …

Multiphoton microscopy has rapidly gained popularity in biomedical imaging and materials
science because of its ability to provide three-dimensional images at high spatial and …

We review the current state of multiphoton microscopy. In particular, the requirements and
limitations associated with high-speed multiphoton imaging are considered. A description of …

We develop a new approach in imaging nonfluorescent species with two-color two-photon
and excited state absorption microscopy. If one of two synchronized mode-locked pulse …

We demonstrate that both oxyhemoglobin and deoxyhemoglobin have sequential two-color,
two-photon absorption properties that can serve as endogenous contrasts in …

For the past two decades, nonlinear microscopy has been developed to overcome the
scattering problem in thick tissue imaging. Owing to its increased imaging depth and high …

We consider a programmable, phase, and amplitude femtosecond pulse shaper based on a
two-dimensional (2D) reflective liquid-crystal (LC) spatial light modulator (SLM). A new zero …

Fluorescence microscopy has been widely used to explore the nanoscale world because of
its superb sensitivity, but it is limited to fluorescent samples. Hence, various spectroscopic …

Nonlinear optical microscopy, based on femtosecond laser spectral reshaping,
characterized and imaged graphene samples made from different methods, both on slides …

We have recently developed a spectral re-shaping technique to simultaneously measure
nonlinear refractive index and nonlinear absorption. In this technique, the information about …
