DEVICE FOR INTRODUCTION OF LASER EMISSION INTO FIBRE Russian patent published in 2008 - IPC G02B6/26 

FIELD: electrical engineering .

SUBSTANCE: device for introduction of laser emission in fibre, which contains optical single-mode or multimode fibres equipped with microlenses that are shaped of transparent materials, differs because microlenses are made of optical glass, refractive exponent of which is higher than the refractive exponent of light conducting thread of fibre, in the shape of sphere that embraces light conducting thread at the end of fibre, and the end surface of fibre is made in the form of polished cylindrical surface, besides, axis of cylindrical surface intersects with fibre axis and is perpendicular to fibre axis.

EFFECT: increases coefficient of emission introduction and reduces dependency of introduction coefficient on misalignment.
