The helion charge radius from laser spectroscopy of muonic helium-3 ions

The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37

Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…

Injection-seeded high-power Yb:YAG thin-disk laser stabilized by the Pound-Drever-Hall method

Manuel Zeyen, Lukas Affolter, Marwan Abdou Ahmed +12

We demonstrate an injection-seeded thin-disk Yb:YAG laser at 1030 nm, stabilized by the Pound-Drever-Hall (PDH) method. We modified the PDH scheme to obtain an error signal free fr…

Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1 hyperfine splitting of muonic hydrogen

J. Nuber, A. Adamczak, M. Abdou Ahmed +46

The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy.…

Pound-Drever-Hall locking scheme free from Trojan operating points

Manuel Zeyen, Lukas Affolter, Marwan Abdou Ahmed +11

The Pound-Drever-Hall (PDH) technique is a popular method for stabilizing the frequency of a laser to a stable optical resonator or, vice versa, the length of a resonator to the fr…

Laser excitation of the 1s-hyperfine transition in muonic hydrogen

P. Amaro, A. Adamczak, M. Abdou Ahmed +43

The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy…

Fiber-integrated spectroscopy device for hot alkali vapor

Josephine Gutekunst, Daniel Weller, Harald Kübler +4

We introduce an all-glass, vacuum tight, fiber-integrated and alkali compatible spectroscopy device consisting of two conventional optical fibers spliced to each end of a capillary…

Laser Spectroscopy of Muonic Atoms and Ions

Randolf Pohl, François Nez, Luis M. P. Fernandes +44

Laser spectroscopy of the Lamb shift (2S-2P energy difference) in light muonic atoms or ions, in which one negative muon is bound to a nucleus, has been performed. The measur…

Thin-disk laser multi-pass amplifier

K. Schuhmann, M. A. Ahmed, T. Graf +8

In the context of the Lamb shift measurement in muonic helium we developed a thin-disk laser composed of a Q-switched oscillator and a multi-pass amplifier delivering pulses of 150…

Improved X-ray detection and particle identification with avalanche photodiodes

Marc Diepold, Luis M. P. Fernandes, Jorge Machado +36

Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work we report on a fitting technique used to account for different detector responses resulting…

Lifetime and population of the 2S state in muonic protium and deuterium

Marc Diepold, Fernando D. Amaro, Aldo Antognini +32

Radiative deexcitation (RD) of the metastable 2S state of muonic protium and deuterium atoms has been observed. In muonic protium, we improve the precision on lifetime and populati…
