TY - JOUR A1 - Vorholt, Christian A1 - Wittrock, Ulrich T1 - Intra-cavity pumped Yb:YAG thin-disk laser with 1.74% quantum defect T2 - Opt. Lett. N2 - We present, to the best of our knowledge, the first intracavity pumped Yb:YAG thin-disk laser. It operates at 1050.7 nm with a quantum defect of just 1.74% due to pumping at 1032.4 nm. Low absorption of the pump light at the pump wavelength of 1032.4 nm is compensated for by placing the disk inside the resonator of another Yb:YAG thin-disk laser which is diode-pumped at 940 nm. The intra-cavity pumped laser has an output power of 10.3 W and a slope efficiency of 8.3% Y1 - 2015 UR - https://www.hb.fh-muenster.de/opus4/frontdoor/index/index/docId/828 UR - https://nbn-resolving.org/urn:nbn:de:hbz:836-opus-8284 VL - 40 SP - 4819 EP - 4822 ER -
