2 μm doubly resonant paramatric oscillator pumped by a thin disk ultrashort laser — •Christian Markus Dietrich, Ihar Babushkin, Laura Rust, José Andrade, and Uwe Morgner — Institut für Quantenoptik, Leibniz Universität Hannover, 30167 Hannover, Germany

Ultrafast light sources with a wavelength around two micrometers are interesting for several experiments like high harmonic generation and investigation of Brunel harmonics [1]. We want to present a doubly resonant optical parametric oscillator (DROPO) for intracavity experiments. Our system is pumped by a home built kerr lens mode locked Yb:YAG thin disk laser with a repetition rate of 34 MHz. The DROPO is operating in a bowtie configuration and uses a BBO as the nonlinear medium. An additional focus point inside the cavity is suitable for further experiments. The wavelength can be rapidly adjusted between the degeneracy point up to 1900 nm + 2300 nm by cavity length tuning alone.
