The following summation of Fourier components with a Gaussian spectral distribution describes a pulse train with a carrier frequency set to zero n2 At Z G cosn 272 Afc r lt13 n2 where the amplitude of the nth spectral component is 2 e G e p n A 160 MHZ is the spacing between longitudinal modes of the laser Afp is the bandwidth of the spectral Gaussian distribution For the HeNe A N 15 GHz With the aid of a computer please make the following graphs of the pulse train 1 For d3 0 make a plot for a n l and b n 3 d Make an additional plot corresponding to the number of modes n you observed lasing in your experiment Describe any differences you see or expect and why 2 For the following set n100 and explain how the phase affects if at all the pulse train eg pulse width pulse timing for the following cases For this exercise please make a plot for both Afp 15 GHz and 150 GHz for each case given below i qquot 0 or any constant ii q is random note a dyfkrent random phase for each d component iii d3 n 7239 linear variation of spectral phase iv d3quot 0005 n2 quadratic variation of spectral phase gt Zoom in on a single pulse for this plot NOTE this last phase simulates the spectral phase acquired by a pulse after passing through dispersive material such as glass 3 Theoretically what is the shortest pulse duration you could expect to measure from the HeNe laser this would be the Fourier transform limited pulse duration
