Dual Yb3+:Lu2O3 thin-disk oscillator with SESAM mode-locking — •Bernhard Kreipe, Jana Kampmann, Luise Beichert, and Uwe Morgner — Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover
We present a multi-crystal oscillator based on two Yb3+:Lu2O3 thin-disks in a symmetrically coupled cavity. The multi-pass geometry of the resonator with 16 passes per round trip enables high outcoupling of the intracavity power greater than 25 %. By splitting the power of a conventional broadband diode to both thin-disks, we achieve more than 50 W of output power in cw operation at 210 W of pump power with a slope efficiency of 40 %. Also the transfer of this power-scaling approach to the pulsed regime in the context of a SESAM mode-locked chirped-pulse oscillator is investigated.
