Abstract:

This grant, through the DOD-University Instrumentation program, was provided to acquire a picosecond laser system for the study of non-linear optical effects as well as for structural characterization of submicron films. The laser system consists of a CW mode-locked Nd-Yag laser Spectra-Physics, Model 300, the output of which, after frequency doubling, is split by a 50 beam splitter to sync pump two dye lasers Spectra-Physics, Model 375. The outputs from these dye lasers are fed into two amplifiers Quanta Ray, Model PDA which are pumped by the second harmonic of a 20Hz pulsed Nd-Yag laser Quanta-Ray, Model DCR-2A. the amplified pulses are 7ps wide with 0.5MJ of pulse energy. The laser system has proven to be extremely versatile and, therefore, valuable for a number of different experiments. This arrangement also gives us the choice to generate tunable picosecond u.v. and IR pulses by mixing either of two dye laser beams with the fundamental from the pulse Yag laser.
