Ultimate stability of active optical frequency standards
Georgy A. Kazakov, Swadheen Dubey, Anna Bychek +3
Active optical frequency standards provide interesting alternatives to their passive counterparts. Particularly, such a clock alone continuously generates highly-stable narrow-line…
Driven electronic bridge processes via defect states in Th-doped crystals
Brenden S. Nickerson, Martin Pimon, Pavlo V. Bilous +7
The electronic defect states resulting from doping Th in CaF offer a unique opportunity to excite the nuclear isomeric state Th at approximately 8 eV via elect…
On an attempt to optically excite the nuclear isomer in Th-229
Simon Stellmer, Georgy Kazakov, Matthias Schreitl +3
We aim to perform direct optical spectroscopy of the Th-229 nuclear isomer to measure its energy and lifetime, and to demonstrate optical coupling to the nucleus. To this end, we d…
Prospects for a bad cavity laser using a large ion crystal
Georgy A. Kazakov, Justin Bohnet, Thorsten Schumm
We propose to build a bad cavity laser using forbidden transitions in large ensembles of cold ions that form a Coulomb crystal in a linear Paul trap. This laser might realize an ac…
Internal conversion from excited electronic states of ions
Pavlo V. Bilous, Georgy A. Kazakov, Iain D. Moore +2
The process of internal conversion from excited electronic states is investigated theoretically for the case of the vacuum-ultraviolet nuclear transition of . D…
Active optical frequency standards using cold atoms: perspectives and challenges
Georgy A. Kazakov, Thorsten Schumm
We consider various approaches to the creation of a high-stability active optical frequency standard, where the atomic ensemble itself produces a highly stable and accurate frequen…
