The objective to this thesis was to improve the procedure for taking unltrafast, time-resolved measurements of photoluminescence from MWIR semiconductors. Previous work has used mode-locked titanium sapphire (Ti:Saph) laser to excite the semiconductor sample and to upconvert the photoluminescene from the semiconductor. Work completed in this thesis improved on the techniques developed during previous work. A synchronous Optical Parameter Oscillator (OPO) will be used to convert the Ti:Saph laser 0.830 micron into 1.3 micron signal and 2.3 micron idler eams. Whereas the Ti:Saph reference and signal beams were too energetic to excite the quantum well (QW) layers of certain MWIR opto-electronic semiconductor structures, the synchronous OPO allows investigation of the active layer by directly exciting the QWs. Photoluminescence was detected from an indium arsenide antimonide (InAsSb) sample with a peak wavelength of 3.8 micron. A detailed procedure for setup of the TRPL experiment using the synchronous OPO is provided.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
