In this thesis, a physically rigorous model for the simulation of internal laser probing techniques for semiconductor power devices is developed which is employed for a thorough analysis of the physical effects during the measurement process. The theoretical studies provide valuable information for developing and optimizing powerful probing techniques which facilitate space-resolved and time-resolved measurements of carrier concentration and temperature profiles. In the second part of this thesis, it will be demonstrated that these techniques constitute an ideal supplement to the well-established electrical characterization methods and thus enable a significantly improved validation and calibration of electrothermal simulation models.
