Pulsed lasers have many applications, but are very complicated to construct. One problem ischromatic aberration, another is aligning the components. Commonly available laser systems canproduce 1 fs (10-¹4 s) pulses.a) how far does light travel in 1 fs?b) If the energy per pulse is 100 mJ, what's the power per pulse (in Watts)?c) calculate the (minimum) spread of frequencies required to produce a 1 fs pulse.d) if the center wavelength is 1 um, what is the range of wavelengths contained in a single pulse?e) common varieties of optical glass have a dispersion An/A2 = 0.025/micron.1) if the index of refraction is 1.51 for λ = 1 um, what is the value of 'n' for the upper and lowerwavelength?2) the focal length of a lens is inversely proportional to the index of refraction: 1/f~ (n-1). Whatis the ratio of the focal lengths for the two extreme wavelengths?3) how much longitudinal chromatic aberration (the difference in focal length between twocolors) is there for a 100 mm focal length lens? How does this compare with (a)? What doesthis tell you?

High-power lasers are used to compress a plasma (a gas of charged particles) by radiation pressure. A laser generating radiation pulses with peak power 1900 MW is focused onto 1.2 mm2 of high-electron-density plasma. Find the pressure exerted on the plasma if the plasma reflects all the light beams directly back along their paths. Number i 1.2E5 * Units N/m^2 or Pa
