Optical refrigeration cools below 100K

Type of Publication: Contribution to a conference
Publication status: Published
Author: Melgaard, Seth; Albrecht, Alexander R.; Hehlen, Markus; Seletskiy, Denis; Sheik-Bahae, Mansoor
Year of publication: 2014
Conference: CLEO : QELS_Fundamental Science, Jun 8, 2014 - Jun 13, 2014, San Jose
Published in: CLEO: QELS-Fundamental Science : part of CLEO ; 8 - 13 June 2014, San Jose, California, United States. - Washington, DC : Optical Society of America, 2014. - FTh4D.4. - ISBN 978-1-55752-999-2
DOI (citable link): https://dx.doi.org/10.1364/CLEO_QELS.2014.FTh4D.4
Summary:
We report a milestone in optical refrigeration, cooling a 10% Yb:YLF crystal to 93K (ΔT~180K); obtaining the coldest solid-state temperature to date. Identification of transition metal impurities via mass spectrometry allows further cooling through purification.
Subject (DDC): 530 Physics
Keywords: Laser cooling; Rare-earth-doped materials
Bibliography of Konstanz: Yes
