摘要：

A physical mechanism of transformations between the amorphous and crystalline phases induced by the electric field of a laser beam is proposed. It creates needle-shaped crystal particles aligned to the beam polarization. The polarization driven orientation of particles can significantly increase the information storage capacity achievable with phase change optical recording. The nucleation and postnucleation stages of the laser field induced crystallization are discussed establishing the conditions under which the polarization aligned particles can be created.
