Product Description
Product Description
The Kerns Technology (2+1)x1 Port Polarization Maintaining Pump Combiner is a high-performance active optical component engineered for high-power fiber laser and amplifier systems. It integrates 2 pump channels (800-1000nm) and 1 signal channel (1030-1080nm or 1450-1600nm) into a single output fiber, while preserving the polarization state of the signal via PM fiber design.
Available in multiple configurations (X/125, X/250, 20/400 fiber types), this combiner delivers industry-leading pump efficiency (up to 95%), low signal insertion loss (≤1.5dB), and high polarization extinction ratio (≥18dB). With a maximum per-pump power capacity of 200W, it supports the high-power demands of modern fiber lasers, while its wide temperature range (-5~+70°C operating) ensures reliable performance in industrial environments.
Product Features
1. (2+1)x1 Port Integration
Combines 2 pump inputs and 1 PM signal input into a single output, simplifying system architecture and reducing component count in high-power laser setups.
2. High Polarization Preservation
Polarization extinction ratio ≥18dB (PM fiber type) maintains the signal’s polarization state—critical for polarization-sensitive laser and amplifier systems.
3. Industry-Leading Pump Efficiency
Pump efficiency up to 95% minimizes power waste, maximizing the output power of fiber lasers and amplifiers (outperforming standard combiners with <90% efficiency).
4. Flexible High-Power Configurations
Multiple fiber type options: X/125, X/250, 20/400 (matches diverse system fiber specifications)
Per-pump power capacity: 50W/100W/200W (customizable for specific power demands)
5. Robust & Customizable Design
Wide operating temperature range (-5~+70°C) for industrial deployment
Customizable package dimensions (D1-D7 or tailored sizes) for space-constrained equipment
Product Applications
This (2+1)x1 PM pump combiner is ideal for:
High-Power Fiber Lasers: Combines multiple pump sources to boost laser output power (common in material processing and cutting systems).

FAQs
Q1: What’s the benefit of a PM pump combiner vs. a non-PM version?
A1: The PM design preserves the signal’s polarization state, which is essential for polarization-sensitive systems (e.g., precision lasers, fiber sensors) where polarization degradation would reduce performance.
Q2: Can I customize the pump power capacity?
A2: Yes. We offer standard per-pump power options (50W/100W/200W) and can design higher-power versions (up to 300W) for specialized high-power laser setups.
Q3: How does fiber type affect performance?
A3: Fiber type (X/125, X/250, 20/400) impacts pump efficiency and power capacity: 20/400 fiber offers the highest efficiency (95%) and power (200W), while X/125 is suited for lower-power, compact systems.
Q4: What’s the typical lifespan of this combiner?
A4: Under normal operating conditions (within power/temperature limits), the combiner has a lifespan of over 5 years, with no maintenance required—critical for industrial laser systems with high uptime demands.
