To improve the quality of education in applied laser physics, a new and innovative educational platform was designed, realized and tested. The system focusses on the improvement of the theoretical, experimental and numerical skills in the topics of ultra-short pulsed fiber based laser systems and related measurement techniques. The main content of the platform is the fundamental understanding of the technologies of an ytterbium-doped fiber based Master-Oscillator Power-Amplifier and a 2nd order intensity autocorrelator. A wide range of system parameters are variable and metrologically accessible. Thus the underlying physical mechanisms are illustrated and, by this the fundamental understanding of the system, improved. To transfer actual industrial and scientific topics into the experimental education of students, the complex lab course aims for a full characterization of the system by experimental work and a numerical analysis by simulating the system dynamics. A state-of-the-art educational tool was created to demonstrate current industrial sys-tems. An amplification of 37.2 dB was achieved. The pulses with a temporal width of 30.6 picoseconds possessed a pulse peak power of 14.2 kW. By the analysis of the material specific spectral properties, the rate equation model can be applied and im-portant system parameters determined.
Um die magnetorsistiven Eigenschaften dünner FeRh-Schichten zu charakterisieren, wurde ein neues Messsystem entwickelt. Für dieses Messsystem wurde ein Probeträger konstruiert der eine Mesung des elektrischen Widerstandes nach Van-der-Pauw in Abhängigkeit der Probentemperatur, eines äußeren Magnetfeldes und dem Energieeintrag durch Ionenbeschuß erlaubt.
