Представлены результаты исследования абляции золота УФ-излучением 266 нм. Показано, что структура депозита на поверхности вокруг абляционных лунок зависит от их глубины. При увеличении глубины лунки осажденные микро- и наночастицы золота приобретают более развитую поверхностную структуру, при этом поверхность вокруг лунок становится насыщенного черного цвета – появляется «черное» золото. Также рассмотрены некоторые особенности и возможные механизмы формирования структур «черного» золота при абляции мощным наносекундным лазерным излучением с длиной волны 266 нм.

The research results of UV 266 nm gold ablation are presented. It is shown that the deposit structure on the surface around ablation pits sharply depends on a pit depth. As the pit depth is increased, gold micro- and nanoparticles acquire a more developed surface structure and the surface around the pits gets deep black color – “black” gold appears. Some features and possible mechanisms of forming “black” gold structures at ablation over the 266 nm powerful nanosecond laser radiation range are also considered.
