In case you are used to seeing the conversion in more of a grid, here is the very last step.

The problem said you have a pulse of 0.528 J, and Robert did all the calculations and got to the fact that each 1 photon is equivalent to 2.93 x 10-19 J.

0.528 J   x        1 photon        =    1.8 x 1018 photons

                    2.93 x 10-19 J
