Simulating the electromagnetic wave of a laser beam is challenging task, which is needed to optimize certain types of solid-state lasers. For this purpose, new time-dynamic and three-dimensional simulation techniques are required. The aim of the research project is to develop such simulation techniques and apply them to lasers that cannot be optimized with current simulation methods. Examples of such lasers are lasers with unstable cavities and passive Q-switches and lasers with special output mirrors. Applications of such lasers can be found in optical metrology and medical applications. The new simulation techniques should enable an accurate simulation of both the amplitude and the phase of the laser beam, such that far field and beam quality can be calculated and optimized. Aside from that, other technical parameters such as pulse width, pulse energy and repetition rate of pulsed lasers should be calculated accurately.
