Reverse pump combiners for high power fibre lasers

LASER COMPONENTS offers high power reverse pump combiners (also called counter pump combiners) which are specifically designed for high power fibre lasers. These combiners are usually mated with a pump combiner in the forward optical path to form a bidirectional pump structure to obtain higher amplification efficiency and output power.

These combiners feature pump wavelength from 800 to 1,000nm and signal wavelength from 1,030 to 1,080nm or 1,450 to 1,600nm, with a total power handling up to 1,000W and a total reverse power handling of 300W.

The devices are available in side-pump (1+1)×1 and (2+1)×1 or end-pump (6+1)×1 and (9+1)×1 configurations, and offer high coupling efficiency with stable and reliable performance.
