OPTICAL FIBRE LASER
摘要:
A method of fabricating a distributed feedback optical fibre laser, comprises the step of exposing an optical fibre (20) to a transverse light beam (30) to form a grating structure in a section of the optical fibre, the writing light beam being polarised in a direction not parallel to the axis of the section (10) of optical fibre (20).
