Solve the following question given below:

Question: In laser eye surgery, the laser emits a 1.32-ns pulse focused on a spot that is 35.4um in diameter.

Part I: If the energy contained in the pulse is 2.54 mJ, what is the power per square meter (the irradiance) associated with this beam?

Part II: Suppose a molecule with a diameter of 0.604 nm is irradiated by the laser beam. How much energy does the molecule receive in one pulse from the laser? (This much energy is likely to dissociate the molecule.)

Please keep answer short and simple and please no copy and paste.
