Product Description

Product Description

The 50W/100W High Power 980-1080nm Faraday Rotator from Kerns Technology is a TGG-based high-performance optical component engineered for extreme-power laser systems. Operating across 980-1080nm (covering key wavelengths like 980nm, 1030nm, 1064nm) with ±5nm bandwidth, it delivers a precise 45° polarization rotation (±2° tolerance at 23°C) to enable non-reciprocal light control.

Built with a rugged 76×38×35mm package, this rotator supports continuous-wave power up to 100W (customizable to 50W/100W) and 10kW peak pulse power (ns-level), making it ideal for high-intensity industrial and R&D setups. It features low maximum insertion loss (1.0dB, +0.3dB with connectors) and exceptional stability: 20dB minimum extinction ratio (PM fiber type) and 0.05ps polarization mode dispersion, ensuring reliable performance across -5~+70°C operating temperatures. It effectively shields laser sources from back-reflections while maintaining polarization integrity in high-gain optical systems.

FAQs

Q1: What is the maximum power this rotator can handle?

A1: It supports continuous-wave power up to 100W (50W/100W options) and 10kW peak pulse power (ns-level). Note that with connectors, the maximum handling power is limited to 1W.

Q2: Can the fiber type and connectors be customized?

A2: Yes. We offer fiber type options (e.g., PLMA-GDF-20/130-M, PLMA-GDF-25/250-M) and connectors (FC/UPC, FC/APC, SC/UPC, etc.), as well as pigtail type and length customization.

Q3: How does connector use affect performance?

A3: With connectors, insertion loss increases by 0.3dB, return loss decreases by 5dB, and extinction ratio decreases by 2dB. Connector key must align with the slow axis for optimal performance.

Q4: What is the operating temperature range?

A4: It operates stably between -5°C and +70°C, with a storage temperature range of -40°C to +85°C. Avoid extreme temperature/humidity environments for long-term reliability.
