Pump-Signal Combiner

PUMP-SIGNAL COMBINER

Pump Signal Combiners, also known as pump couplers, are specialized fiber optic components designed for directing both pump and signal light into amplifiers or laser fibers. Engineered for high-power applications, these combiners ensure reliable performance in demanding environments, making them essential for advanced fiber laser and amplifier systems.

PSC611: Pump-Signal Combiner, (6+1) x 1

The PSC611 is an all-glass, pump-signal combiner that offers:

Information loss of 0.5 dB or less on all channels
Polarization extinction ratio (PER) greater than 23 dB maintained through the signal channel
Flexible and scalable design, based on Chiral Photonics’ proprietary pitch reducing optical fiber array (PROFA) technology, with independent control of channel spacing, mode field diameter, and channel count.

Speak to us about your custom or OEM needs as this design facilitates use at 1060 nm as well as the shown 1550 nm configuration. The design can also be modified to suit your specific fiber needs:
