1064nm Polarization Beam Combiner/Splitter (GK-PBC/PBS Series)

The 1064 nm Polarization Beam Combiner/Splitter is a compact high performance lightwave component that combines two orthogonal polarization signals into one output fiber.The most common application is to combine the light of two pump lasers into one single fiber to double the pump power. The typical configuration uses two PM fibers as input and SM fiber as output. The device can also be used as a beam splitter.

product description

The GKER Photonics 1064 nm Isolator Polarization Beam Combiner/Splitter is a high-performance optical device designed to combine two orthogonal polarization signals into a single output fiber while providing optical isolation. This compact device integrates the functions of a polarization beam combiner and an optical isolator, making it ideal for applications where both power amplification and signal stability are critical.

This component is commonly used in fiber laser systems, such as EDFA and Raman amplifiers, to efficiently double pump power by merging the outputs of two pump lasers. With its low insertion loss, high isolation, and high extinction ratio, this device ensures minimal signal degradation and high polarization purity. The device supports continuous wave optical power up to 300 mW and is compatible with PM 980 Panda Fiber for Ports 1 & 2 and HI 1060 or PM Panda Fiber for Port 3.

Designed to operate reliably within a temperature range of -5°C to +50°C, this combiner/splitter offers outstanding environmental stability, making it a robust choice for demanding optical systems. Whether you're working in telecom, research, or industrial applications, this product delivers the precision and reliability needed to maintain optimal system performance.
