Significance Photoacoustic imaging (PAI) enables the visualization of optical contrast with
ultrasonic imaging. It is a field of intense research, with great promise for clinical application …

Near-infrared photoacoustics receives increasing interest as an intravital modality to sense
key biomolecules. One of the most central types of biomolecules of interest are lipids as they …

Originally introduced in 2005 for high-speed optical coherence tomography, the rapidly
wavelength-swept Fourier-domain mode-locked (FDML) laser still, to this day, enables …

We introduce a fully-integrated two-color sub-nanosecond fiber laser system that
incorporates a backward-pumped polarization-maintaining (PM) Raman phosphosilicate …

Imaging increasingly large neuronal populations at high rates pushed multi-photon
microscopy into the photon-deprived regime. We present PySight, an add-on hardware and …

We demonstrate a nanosecond 560 nm pulse source based on frequency-doubling the
output of a combined Yb-Raman fiber amplifier, achieving a pulse energy of 2.0 µJ with a …

Stimulated Raman scattering (SRS) microscopy for biomedical analysis can provide a
molecular localization map to infer pathological tissue changes. Compared to spontaneous …

Four-wave mixing (FWM) enables the generation and amplification of light in spectral
regions where suitable fiber gain media are unavailable. The 1300 nm and 900 nm regions …

Wavelength-swept lasers enable high-speed measurements in absorption spectroscopy,
Raman spectroscopy, nonlinear Raman hyperspectral microscopy, rapid confocal …

Coherent Raman scattering microscopy utilizing bioorthogonal tagging approaches like
isotope or alkyne labeling allows for a targeted monitoring of spatial distribution and …
