Abstract : The report is on elucidating the properties of ultrashort pulses emitted by mode-locked neodymium and ruby lasers. The point of departure is to measure properties of individual ultrashort pulses rather than as an average of many pulses. An experimental approach to obtain the pulse width and energy is outlined including approximate results. More accurate measurements is awaiting more accurate computer solutions of associated partial differential equations. As a side, these experiments lend themselves to complementary studies of the chemical dynamics of Q-switch dyes such as the decay times on a time scale comparable to ultrashort pulse durations.
