Germany -- Berlin,
Lumics a manufacturer of pump laser modules and laser chips introduces the
un-cooled LU0975T040 laser module with up to 4W output power from a multi
mode fiber. Lumics introduces this laser in a un-cooled TO220 package
coupled with a 100/125um multimode fiber with a numerical aperture of 0.22.
The fiber is terminated with a standard 2.5mm diameter ceramic ferrule.
FC/PC or SMA connectors are optional.
The new package
design is used as a platform for the a new series of high power single
emitter laser diodes at different pump wavelength with an excellent cost /
performance ratio. Combined pump laser modules which use several single
emitter allow an easy scalable output power. Target applications
include industrial Erbium Ytterbium fiber lasers and Erbium doped fiber
The new generation
of high power modules allows a cost effective laser system design with an
The complete module assembly is based on fully automated active fiber
Production is ISO
9001 approved with several screening steps throughout the chip manufacturing
and module assembly process. The operating current is specified with
typically 6.5A. The very low forward voltage is specified with max. 3.2V.
The threshold current is typically 245mA. The performance of the device is
based on Lumics propriety chip technology which ensure very high reliability
with a breakthrough in laser facet passivation.
