Description of Measurement
The laser spectrum after the main amplifier is taken at the output of the main amplifier enclosure. The spectrum is measured with an Ocean Optics HR2000+ spectrometer. The spectrometer fiber is inserted into the back of a foam block placed in the laser path.
For each measurement, the spectrum is shown in the left plot and the resulting transform limited pulse is shown in the right. The FWHM and 1/e^2 values are measured from the raw data. The fit parameters are shown in the upper right of each plot.
