Ultrafast Microscopy
Ultrafast microscopy is a cutting-edge scientific tool that integrates ultrafast laser technology with microscopic imaging techniques. It is designed to simultaneously achieve extremely high temporal resolution (from femtoseconds to attoseconds) and spatial resolution (from nanometers to submicrometers), enabling real-time observation of ultrafast dynamic processes in the microscopic world. The advancement of this field has, for the first time, allowed humanity to "film" the trajectories of atoms, molecules, electrons, and other microscopic particles on ultrafast timescales, playing an indispensable role across a wide range of disciplines—including physics, chemistry, materials science, and the life sciences.
CARS and SRS Microscopy
A nonlinear vibrational imaging technique that uses a pump–Stokes–probe four-wave mixing process to generate a resonant anti-Stokes signal, enabling label-free chemical mapping with high speed and intrinsic vibrational contrast.
Ultrafast Electron Microscopy
A technique that combines femtosecond laser excitation with pulsed electron beams to image transient structural dynamics (e.g., lattice vibrations, phase transitions) with both sub-picosecond temporal resolution and nanometer spatial resolution.
Three-Photon Microscopy
A deep-tissue imaging technique that uses three near-infrared photons for simultaneous excitation, significantly reducing scattering and background fluorescence, enabling high-resolution imaging at depths beyond the reach of two-photon microscopy.
