DEVICE FOR PHASE SHIFT OF LASER BEAM STRUCTURE Russian patent published in 1996 - IPC

Abstract RU 2061249 C1

FIELD: methods for exposing physical and medical objects to laser light. SUBSTANCE: laser beam runs through phase plate and lens which is made from crystal. Two waves are generated at output of this unit. Usual wave and unusual waves have own distribution of intensity shaped as periodical maximums inside dispersal circle. Common pattern from two waves has greater degree of density of filling dispersal circle with maximums with respect to density of one wave. EFFECT: increased quality of phase shift. 2 dwg
