Transient absorption microscopy adds a spatial resolution to the quantitative characterization of time-dependent absorption of an optically excited sample.

Nonlinear microscopy is a powerful technique for imaging inside living organisms with a submicrometer resolution at millimeter depths.

Ultrafast electron microscopy is a pump-probe technique in which an ultrafast laser pulse excites the material, and a delayed electron pulse detects the response.

Coherent anti-Stokes Raman scattering (CARS) and stimulated Raman scattering (SRS) are used for high-speed and high-sensitivity label-free vibrational imaging.
