Abstract:
     A method for manufacturing prism using Bragg raster of optical fibre features that the bottom of an isosceles molten quartz prism is put closely over optical fibre, an ultraviolet beam is incident from the top angle of prism to generate two light beams, which form a coherent field (the strongest coherent field is at outside of prism bottom), and the optical fibre is put in the strongest coherent field.
