Generation of continuous-wave laser light at 148.4 nm using cavity-enhanced second harmonic generation in
Keerthan Subramanian, Hiroki Tanaka, Simon J. Herr +22
The development of a nuclear optical clock based on \textsuperscript{229}Th is expected to influence the next generation of time and frequency standards. At its heart is the need f…
Laser fluence-dependent production of molecular thorium ions in different charge states for trapped-ion experiments
Jonas Stricker, Jean Velten, Valerii Andriushkov +8
Thorium ions and molecules, recognized for their distinctive nuclear and atomic attributes, are central to numerous trapped-ion experiments globally. Our study introduces an effect…
thin films for solid-state nuclear clocks
Chuankun Zhang, Lars von der Wense, Jack F. Doyle +11
After nearly fifty years of searching, the vacuum ultraviolet Th nuclear isomeric transition has recently been directly laser excited [1,2] and measured with high spectrosc…
Tunable VUV Frequency Comb for Th Nuclear Spectroscopy
Chuankun Zhang, Peng Li, Jie Jiang +4
Laser spectroscopy of the Th nuclear clock transition is necessary for the future construction of a nuclear-based optical clock. Precision laser sources with broa…
The Th isomer: prospects for a nuclear optical clock
Lars von der Wense, Benedict Seiferle
The proposal for the development of a nuclear optical clock has triggered a multitude of experimental and theoretical studies. In particular the prediction of an unprecedented syst…
A laser excitation scheme for Th
Lars von der Wense, Benedict Seiferle, Simon Stellmer +4
Direct laser excitation of the lowest known nuclear excited state in Th has been a longstanding objective. It is generally assumed that reaching this goal would require a c…
A VUV detection system for the direct photonic identification of the first excited isomeric state of Th
Benedict Seiferle, Lars von der Wense, Mustapha Laatiaoui +1
With an expected energy of 7.6(5) eV, Th possesses the lowest excited nuclear state in the landscape of all presently known nuclei. The energy corresponds to a wavelength o…
