diode pumps in spectral region 910 - 980 nm are required for optical pumping of fibre
devices based on rare-earth doped double clad fibres. In many applications such as three
level fibre lasers high brightness pump sources are required.
ULTRA is based on
state of the art technology of highly reliable single stripe laser diodes with life-time
exceeding 100,000 hours and can operate without TE cooling at ambient temperatures
exceeding 60є C.
delivers up to 6 W of CW optical power in a 35 µm, 0.22 NA all glass multimode optical fibre while
the state of the art optical packaging provide unprecedented brightness and reliability.
Power brightness delivered by ULTRA is comparable with that of laser diode chips and it
makes this pumps unavoidable tool in development of advanced fibre lasers and amplifiers
such as 980 nm fibre lasers and cladding pumped erbium-doped fibre amplifiers. ULTRA comes
in two basic configurations with 3 W and 6W of output power. Operating wavelength is 915
or 970 nm although other wavelengths are also available on request
