This thesis covers an in-depth analysis of the pulsed laser system to be used in the developing a linear technique for the time domain study of the change in coherence of atomic superposition states for the Ytterbrium atom due to phase-interrupting collisions. The hybrid synchronously pumped dye laser yielded optimally shaped sub-picosecond pulses at the 555.6 nanometer wavelength. Comparison of the results for the experimental trials at the 576 and 555.6 nanometer wavelengths yielded an experimental value for the dephasing time, T sub 2 621 picoseconds, of the DMETCI dye used as a saturable absorber dye for the first time.
