Pulsed lasers used in science and medicine produce very short bursts of electromagnetic energy. if the laser light wavelength is 1062 nm (this corresponds to a neodymium-yag laser), and the pulse lasts for 34 picoseconds, how many wavelengths are found within the laser pulse?
how short would the pulse need to be to fit only one wavelength?
