The first rare-earth-doped fiber lasers were operated in the early 1960s, and produced a few
milliwatts at a wavelength around 1 mum. Since the beginning of the decade, an enormous …

We have demonstrated a highly-efficient cladding-pumped ytterbium-doped fiber laser
generating 1.36 kW of continuous-wave output power at 1.1 μm with 83% slope efficiency …

This paper reviews current fibre laser technology and new directions that will improve their
performances. Grating technology and the ability to provide high power operation has driven …

We report on a novel ytterbium-doped fiber design that combines the advantages of rod and
fiber gain media. The fiber design has outer dimensions of a rod laser, meaning a diameter …

We demonstrate an all-fiber 7x1 signal combiner for incoherent laser beam combining. This
is a potential key component for reaching several kW of stabile laser output power. The …

In this paper we review the damage mechanisms that need to be considered when building
high power fibre lasers. More specifically we look at thermal issues, optically induced …

100W linear-polarized single-mode CW emission is demonstrated in an all-fiber format at
1566 nm. The Yb 3+/Er 3+ doped fiber laser has an extinction ratio> 20 dB and M 2< 1.1 …

We report on continued progress in nLIGHT's high power and high efficiency single emitter
laser diodes from 915 nm to 980 nm range used for industrial and pumping applications …

A new type of monolithic high-power fiber laser with a multifiber series and distributed
pumping is put forward. The distributed pumping multifiber series fiber laser is a good …

High-power continuous wave (CW) fiber lasers with excellent beam quality continue to drive
demand for higher brightness pump modules at 920 nm and 976 nm. Over the last decade …
