Collinear laser spectroscopy in the 1s2s3S1→1s2p3P0,2 transitions of helium-like 11B3+ was performed using the HITRAP beamline at the GSI Helmholtz Centre. The ions were produced in an electron beam ion source, extracted, and accelerated to a beam

High-precision quasisimultaneous collinear/anticollinear laser spectroscopy was used to measure the 4s^{2}S_{1/2}→4p^{2}P_{1/2} (D1) and the 4s^{2}S_{1/2}→4p^{2}P_{3/2} (D2) as well as the three 3d→4p transitions in the naturally abundant Ca^{+

A laser wavelength meter was calibrated to ±1 MHz 1 $$\sigma$$ using transitions in molecular iodine at around 700 nm, where precise experimental measurements of iodine lines are sparse. Two saturation absorption spectroscopy systems were used to me

We demonstrate an application of a liquid-metal ion source for collinear laser spectroscopy in proof-of-principle measurements on naturally abundant ${\mathrm{In}}^{+}$. The superior beam quality, i.e., the actively stabilized current and energy of a

We present a new collinear laser spectroscopy setup that has been designed to overcome systematic uncertainty limits arising from high-voltage and frequency measurements, beam superposition, and collisions with residual gas that are present in other

A laser ablation ion source has been built and tested at the COALA beamline. Time-of-flight measurements for various elements are sufficiently accurate to confirm the production of the intended ion species. Furthermore, the isotope shift between 40Ca
