Violet laser diodes for laser cooling and trapping of ytterbium atoms

Abstract

We report the construction of frequency-stabilized high-power violet laser diodes for laser cooling and trapping experiment of ytterbium atoms. An external-cavity master laser of which frequency was stabilized to the ytterbium cooling transition at 398.9 nm was built and used to build a frequency-stabilized high-power slave laser (25 mW) by injection seeding technique.
