RoHS compliant
Oclaro's new multimode single emitter based laser
diode module BMU25-9xx-01/02-R has been designed
to provide an increased power output enabling fiber
laser and direct system manufacturers to generate
higher powers with fewer modules, allowing for more
compact pump configurations, greater pump block
efficiency and simplification of packaging. Its compact
design reduces the footprint of fiber laser pump stages
The module includes multimode laser diodes with E2
front mirror passivation that prevents Catastrophic
Optical Damage (COD) to the laser diode facet even
at very high power levels. The laser diodes are
connected in series to allow for fast current switching.
The module includes a feedback protection filter that
protects the laser diodes from harmful fiber laser
wavelength feedback light.
