You measured their pulse duration (i.e. autocorrelation trace) and spectrum using an autocorrelator and spectrometer, respectively. The data were compiled in an Excel file (A4_data.xlsx). Using the provided data: 1) plot the graphs of pulse duration and corresponding spectrum; 2) calculate the FWHM (full width at half-maximum) of spectrum and pulse duration; 3) find the time-bandwidth product of the pulses and compare it with the one of transform-limited pulses assuming that your pulses have a sech? (i.e. hyperbolic secant squared) temporal profile; 4) find the number of oscillating longitudinal modes that were locked in phase to produce the pulses if laser cavity was 1.5 m long.
