Photoacoustic imaging (PAI) is a rapidly growing field which offers high spatial resolution
and high contrast for deep‐tissue imaging in vivo. PAI is nonionizing and noninvasive and …

A first approach toward understanding the targeted design of molecular photoacoustic
contrast agents (MPACs) is presented. Optical and photoacoustic Z-scan spectroscopy was …

A phase modulation technique to sensitively and selectively isolate multiple-quantum
coherences in a femtosecond pump-probe setup is presented. By detecting incoherent …

Imaging the intrinsic optical absorption properties of nanomaterials with optical microscopy
(OM) is hindered by the optical diffraction limit and intrinsically poor sensitivity. Thus …

Recent work applying multidimentional coherent electronic spectroscopy at dilute samples
in the gas phase is reviewed. The development of refined phase cycling approaches with …

Wave-front shaping techniques enable focusing and imaging through scattering media.
Unfortunately, most approaches require invasive feedback inside or behind the sample, or …

In diagnostics, photons are used in basic methods such as computed tomography (CT) and
positron emission tomography (PET), which are pivotal tools for high-resolution, non …

We propose photoacoustic microscopy using ultrashort pulses with two different pulse
durations in the range from femtoseconds to picoseconds. The subtraction of images for …

Simultaneous two-photon absorption to one-photon forbidden electronically excited states of
diphenylacetylene (DPA) and diphenylbutadiyne (DPB) was investigated by means of highly …

By combining phase-modulated nonlinear spectroscopy with second harmonic generation,
the concept of phase-modulated harmonic light spectroscopy is introduced. Simultaneous …
