Pulsed lasers are powerful sources of nearly monochromatic radiation. Lasers that emit photons in a pulse of 5.00 ns duration with a total energy in the pulse of 0.175 J at 875 nm are commercially available. a. What is the average power (energy per unit time) in units of watts (1 W=1 J / s) associated with such a pulse? b. How many photons are emitted in such a pulse? | Numerade
