Discuss CARS (Coherent Anti-Stokes Raman Scattering)microscopy and its applications.
I dont understand the process which two lasers (stokes &pump) interact together in the sample and causing a vibrationalmode. Please describe this part well. Thank you. and how is thesignal transferred so the imaged can be created?

CARS process can be physically explained by using either a classical oscillator model or by using a quantum mechanical mode 1 Classical Classically the Raman active vibrator is modeled as a harmonic oscillator with a characteristic frequency of v The difference frequency pS between the pump and the Stokes beams drives this oscillator instead of single optical wave When the difference frequency pS approaches v the oscillator is driven very efficiently On a molecular level this implies that the electron cloud surrounding the See Answer
