Abstract
In this paper the results of microstructuring of monocrystalline silicon by series of nanosecond Yb-fiber laser pulses are presented. It is shown that nanosecond Yb-fiber laser can be successfully applied for creation of microrelief consisting of microcones arrays. Obtained relief provides a reduction of the reflection coefficient below 10% in visible range of the spectrum. It is also established that for creation of microconical relief by nanosecond Yb-fiber laser it is advisable to use "short" nanosecond pulses with pulse durations from several nanoseconds to several tens of nanoseconds.
