"Ultrafast" lasers produce bursts of light that last only on the order of 10 fs. Because of the uncertainty principle, such short bursts have a relatively large uncertainty in frequency and wavelength. An ultrafast laser has a central wavelength of 550 nm. What pulse duration (in fs) would result in a spread of wavelengths that just covered the visible spectrum, 400 nm to 700 nm?
