High-field photoionization of Beryllium using a low-cost solid-state laser

The generation of a pure sample of ions is a prerequisite for a variety of experiments in atomic and molecular physics, in particular using ion traps. Resonant laser photoionization has the advantage of being element and isotope selective, therefore permitting precise control of the composition of the generated ionic species. In this talk we describe experiments employing a novel system for the photoionization of Beryllium at a 2T magnetic field in a Penning trap. Our system is based on injection-locking of a low-cost, high-power multimode diode at 470nm which can then be frequency doubled to the relevant wavelength near 235nm. The optical setup and its application will be presented.
