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 vibrational mode. Please describe this part well. Thank you. and how is the signal transferred so the imaged can be created?

*Bragg Scattering What is the Bragg Scattering angle (i.e. the angle, in degrees, between the incoming incident beam and the reflected beam) for electrons scattered from a nickel crystal if their energy is 63 eV? The spacing between Ni Bragg planes is 0.215 nm. Give your result to 3 significant figures.

Give a brief account of a. [5 marks] Rayleigh scattering, b.[5 marks] the photoelectric effect, c. [5 marks] the Compton effect and d. [5 marks] pair/triplet production. For each of them, describe the phenomenon, account for it in terms of physical principles, and state the photon energy range and atomic number Z of target material over which it is important.
