The extreme intensities which can be achieved by focusing ultrashort laser pulses, make them very interesting, e.g. for materials processing.
The spatial and temporal field distribution of a laser pulse significantly affects the achievable power in the focus of an optics. Therefore, it is essential to know this field distribution and, if necessary, be able to change it adequately.
The field distributions of ultrashort laser pulses can be considerably improved and optimally adapted to specific applications by using appropriate tools for design and analysis. Numerical simulations serve as the basis for analysis of arbitrary optical systems and design of customized optics.
The manipulation of the spatial and temporal field distributions of the laser pulses is accomplished by means of suitable phase elements.
