Optische Komponenten Charakterisierung mit Ultrakurzpulslaser — •Thomas Stubbe, Kai Starke, Lars Jensen, Marco Jupé, Istvan Balasa, and Detlev Ristau — Laser Zentrum Hannover e.V., Hollerithallee 8, 30419 Hannover

Applications of ultrashort pulse laser nowadays are used in areas like medicine, basic research, laser machining and many high other technology fields. The results are high innovation laser tools and the motivation to turn these results into compact and high efficiency laser systems and into economic success. Because of the fast development in the optical components have to keep pace with the rapid evolution of requirements which are produced in a regular production chain. Therefore to obtain the ability to compete with other foreign countries, the cooperative project OKuLas, Optische Komponenten für Ultrakurzpulslaser starts to fix the numerated problems. The Laser Zentrum Hannover (LZH), in cooperations with LINOS, started to work on nonlinear absorption with ultra short pulsed Lasers. The difference compared to other absorption experiments at the LZH is that volume optics will be measured. Due to different geometrical crystals, two mounts are in a design process and will be tested to study if there is a difference in convection or the direct contact on the temperature sensors. Also a demonstration of a test set-up for a standardized absorption measurement of crystals in u.s.p. laser systems will be shown. Results will be presented as well as recently conducted results concerned to LC of coated fs -optics.
