Application, measurement and generation of ultra short Laser pulses
Lecture WS 2007/2008
Carsten Fallnich
Di. 10.15 - 11.45 SR AP (Room 222)
Already a short time after the realization of the principle of laser approximately 40 years ago ultra short light impulses could be generated and measured by using coupling of modes. But for considerable applications it takes time until the middle of the nineties, especially in industry and medicine. The decisive aperture succeeded with the development of new optical amplification media and new coupling methods of modes and the so improved comprehension of generation, measurement and manipulation of ultra short light pulses.
In addition to fundamentals modern potentials of application and nonlinear physics "of" and "with" ultra short light pulses will be introduced in the frame of the lecture. Thereby, the advantages as well as the existing constrictions of the required techniques should be explained for using their possibilities (realistic and successful). Dependent on number and interest of the participants it is planned to show small experiments etc. for better exemplification.
