2. Understand the material properties that govern the optical cattering within biological tissues.

3. Understand the principles that govern radiative transport in absorbing and scattering tissues.

4. Understand the principles governing laser-induced thermal processes in tissue.

5. Determine the magnitude of thermo-elastic stresses generated by pulsed laser irradiation.

6. Determine if thermal or mechanical confinement is established in a pulsed laser application.

7. Understand the layout of a Jablonski diagram and the radiative and non-radiative processes that it depticts.

8. Be exposed to photochemistry and photodymanic therapy.

9. Be exposed to the governing principles of optical coherence and multi-photon microscopy techniques.

10. Be familiar with the capabilities of highly focused laser beams for cellular microsurgery and micromanipulation.
