Abstract

Microstructures with the total length of hundreds of μ m were induced by fixing the focal point of the femtosecond laser at a certain depth in the bulk of SrTiO₃ crystal. By different combination of the focusing conditions with the laser parameters, different morphologies have been observed, such as void array, necklace-shaped structures, continuous/ segmental filaments and etc. The possible mechanism of the formation of those diversiform structures is discussed.
