The Ti:Sapphire laser has been in the forefront of ultra-fast optics for over ten years now, and is still considered one of the most useful lasers for ultra-fast optics. This project has involved the construction of a Ti:Sapphire laser to produce light pulses on the order of ~10fs. Due to the difficulty in measuring a light pulse of that is this short, a Frequency Resolved Optical Gating (FROG) system has been employed. This FROG system is to be used for obtaining information about the length, frequency, intensity and phase of the pulses. Unfortunately, I have been having difficulty obtaining results so this thesis will deal mainly with the theory behind these concepts.
