Microstructures induced in the bulk of SrTiO3 crystal by a femtosecond laser.
Microstructures with the total length of hundreds of mu m were induced by fixing the focal point of the femtosecond laser at a certain depth in the bulk of SrTiO(3) 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.
