Product Description

Product Description

The 20W High Power 780-1064nm Faraday Rotator from Kerns Technology is a high-performance optical component engineered for demanding high-power laser systems. Operating across a broad wavelength range of 780-1064nm (covering key wavelengths like 780nm, 808nm, 850nm, 980nm, 1030nm, 1064nm), it delivers a precise 45° Faraday rotation (with ±2° tolerance at 23℃) to control light polarization reliably.

Built with advanced optical materials and a rugged 58×28×26mm package, this rotator supports continuous-wave power up to 20W (customizable to 0.5W-20W) and peak pulse power of 10kW (ns 级), making it suitable for high-intensity optical setups. It features low maximum insertion loss of 1.0dB (0.3dB higher with connectors) and exceptional stability, withstanding operating temperatures from -5℃ to +70℃. Whether for fiber lasers, industrial processing, or laboratory R&D, it ensures non-reciprocal polarization control and protects sensitive optical components from back-reflection damage.

FAQs

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

A1: It supports continuous-wave power up to 20W (customizable from 0.5W to 20W) and peak pulse power of 10kW (ns 级). Note that when using connectors, the maximum handling power is limited to 1W.

Q2: Can the fiber type and connector be customized?

A2: Yes. We offer various fiber type options (such as PM980, HI1060, PLMA-GDF-10/125-M) and connector types (FC/UPC, FC/APC, SC/UPC, SC/APC, etc.). Pigtail type and fiber length can also be customized to your needs.

Q3: How does the insertion loss change when using connectors?

A3: Without connectors, the maximum insertion loss is 1.0dB. When connectors are installed, the insertion loss increases by 0.3dB, and other performance parameters like return loss and extinction ratio will have slight changes (return loss decreases by 5dB, extinction ratio decreases by 2dB).

Q4: What is the operating temperature range of this product?

A4: It operates stably between -5℃ and +70℃, and the recommended storage temperature range is -40℃ to +85℃. Avoid extreme temperature and humidity environments to ensure long-term reliability.

Q5: Does the rotator require specific axis alignment during installation?

A5: Yes. It adopts dual-axis operation design, and connectors need to be aligned with the slow axis during installation to ensure optimal polarization control performance.
