A ruby laser produces radiations of wavelength, `662.6nm` in pulse whose duration are `10^(-9)s`. If the laser produces `0.39 J` of energy per pulse, how many protons are produced in each pulse?

A pulsed laser emits light at a wavelength of 694.4 nm. The pulse duration is 12 ps, and the energy per pulse is 0.150 J. (a) What is the length of the pulse? (b) How many photons are emitted in each pulse?

A laser used to weld detached retains emits light with a wavelength 652 nm in pulses that are of 20ms duration. The average power during each pulse is 0.6W. The energy in each pulse and in a single photon are
