A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

Laser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

Laser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.
