Abstract:
Laser cooling of beryllium ions is a key enabler for quantum technologies such as e.g. optical clocks [1] or crystallization of highly charged ions [2] . It requires laser light at 313 nm, which is usually generated via second harmonic of light at 626 nm. The wavelength of 626 nm also requires either dye lasers or a complex set of solid state or fibre lasers, which defy miniaturization. Semiconductor laser based solutions are here preferred, as they enable achieving a degree of miniaturization, which allows possible real world applications, and a few semiconductor laser-based solutions were already presented [3] , [4] .
