Problem 3) Ultrashort laser pulses and the uncertainty principle: Many varieties of lasers emit light in the form of pulses rather than a steady beam. A tellurium-sapphire laser can produce light at a wave-length of 800 nm in ultra-short pulses that last only 4.00-10-15 s. The energy in a single pulse produced by one such a laser is 2.00 - 10-6 J, and the pulse propagate in the positive x-direction. Find a) the frequency of the light, b) the energy and minimum energy uncertainty of a single photon in the pulse, c) the minimum frequency uncertainty of the light in the pulse, d) the spatial length of the pulse, in meters and as a multiple of the wavelength, e) the momentum and minimum momentum momentum uncertainty of a single photon in the pulse f) the approximate number of photons in the pulse
