Narrow-separation FBGs increase fibre capacity
Southampton Photonics has shipped what are believed to be the first commercially available 25GHz-channel-separation fibre Bragg gratings (FBGs).
Fibre Bragg gratings increase channel capacity
Southampton Photonics has formally launched its BragNet family of fibre Bragg gratings, claimed to be the most advanced of their type.
In published experiments, over 270W of single-mode output power at 1080nm from an ytterbium doped fibre laser (YDFL) and over 100W of single-mode output power at 1565nm from an erbium-ytterbium fibre laser have been achieved.
SPI believes these are the highest powers ever produced using ytterbium and erbium-ytterbium single-mode fibre lasers.
Ytterbium-doped fibre lasers are amongst the most efficient of all rare-earth doped fibre lasers, and erbium-ytterbium codoped fibre lasers are the most efficient type of high-power laser of any kind operating in the "eye-safe" wavelength region at around 1550nm.
With the appropriate fibre designs, SPI expects single-mode fibre lasers with 1kW of output power to be realisable in the not too distant future.
It is also anticipated that the recent rapid improvements will continue and will spread to more refined fibre lasers with single polarisation, narrow linewidths and pulsed sources.
Stuart Woods, SPI's Director of Business Development, commented: "This development is typical of the ground-breaking work underway at SPI to bring disruptive, high-power fibre technology to market offering both lower unit and total ownership cost for customers in a variety of applications".
World record-beating results from a 980nm laser using SPI patented ytterbium ring-doped cladding pumping technology, will also be presented at the Advanced Solid State Photonics Conference in San Antonio, Texas in early February.
