Pulse laser and spectral width help!

  1. Apr 6, 2009 #1
    A pulse 300ns long is made using a continuous wave laser and a very(very) fast shutter. What is (approx.) the minimum spectral width of the pulse?


    I have no idea where to start. For starters what is the spectral width? and how would i go about solving this problem. Not looking for a solution just an idea of how to get it!
