Exploring $I^\pm$ - and $I^^{2}$ -decay-induced quenching of the $^{229}$ Th nuclear-clock isomer in solid-state hosts

Y. Elskens, M. Athanasakis-Kaklamanakis, S. Arasada Pradeep +52

The radiative decay dynamics of an ensemble of $^{229 m}$ Th nuclei embedded in CaF $_{2}$ and MgF $_{2}$ is investigated. The isomer is populated through $I^^{2}$ decay of $^{229}$ Ac…

Cascaded multi-harmonic generation in a \b{eta}-BBO crystal reaching 133 nm from a single 800 nm pump beam

J. Seres, E. Seres, T. Schumm

Nonlinear crystals are widely used to efficiently generate second or third harmonics, and also for frequency mixing. Generation of multiple cascaded harmonics simultaneously, howev…

Laser-Induced Quenching of the Th-229 Nuclear Clock Isomer in Calcium Fluoride

F. Schaden, T. Riebner, I. Morawetz +11

The 10-minute radiative lifetime of the first excited $^{229}$ Th $^{4 +}$ nuclear state in ionic crystals provides narrow spectroscopic linewidths, enabling the realization of a soli…
