Fibre Lasers

David Hanna


The first fibre laser, described by Snitzer, was also the first glass laser. The glass fibre, doped with trivalent neodymium ions (Nd3+) was transversely pumped by a flash lamp. The fibre geometry was chosen to exploit the brightness enhancement of pump light in the core after passing through the clear cladding, and also to provide a structure which was more forgiving of the optical inhomogeneities of the doped glass. These early fibres clearly demonstrated the capability for very high gain, with 47dB measured at 1.063μm, even if the transverse pumping geometry was of very low efficiency.
