Mv. Vasnetsov et al., BIRTH AND EVOLUTION OF WAVE-FRONT DISLOCA TIONS VIA OPTICAL-DAMAGE INLINBO3 CRYSTAL, UKRAINSKII FIZICHESKII ZHURNAL, 39(5-6), 1994, pp. 542-544
Birth and evolution of wave-front dislocations in laser beams via the
optical damage effect in photorefractive crystal were observed and stu
died. Pairs of opposite-sign screw dislocations and edge dislocations
appear in transmitted beams perturbed the optical damage.
