Query: Coherent anti-Stokes Raman scattering through thick biological tissues
  by single wavefront shaping   Coherent Anti Stokes Raman Scattering (CARS) offers many advantages for
nonlinear bio-imaging, thanks to its sub-cellular spatial resolution and unique
chemical specificity. Its working principle requires two incident pulsed laser
beams with distinct frequencies to be focused in space and time, which focus
quality however rapidly deteriorates when propagating at large depths in
biological tissues. The depth limits of CARS and the capability of wavefront
correction to overcome these limits are currently unknown. In this work we
exploit the spectral correlation properties of the transmission matrix of a
scattering medium in a pulsed regime, to recover coherent focusing for two
distant incident CARS wavelengths which propagation is initially uncorrelated.
Using wavefront shaping with a single spatial light modulator, we recover CARS
generation through thick mice spinal cord tissues where initially no signal is
measurable due to scattering, and demonstrate point scanning over large field
of views of tens of micrometers.
