Product Description:

Fiber-Free Space Isolators are essential components for maintaining the stability and performance of optical systems, particularly in fiber laser applications. Our isolators can be categorized into two types: non-expanded-beam isolators and expanded-beam isolators.

The non-expanded-beam isolator consists of a birefringent crystal, Faraday rotator, half-wave plate or polarizer, and collimator. It effectively stabilizes the optical system in fiber laser setups, ensuring reliable operation.

On the other hand, the expanded-beam isolator incorporates a collimator, birefringent crystal, Faraday rotator, half-wave plate or polarizer, and beam expander. This configuration produces an output beam with excellent beam quality and a small divergence angle.

At CASTECH, we utilize high-quality crystals and optical components to fabricate Fiber-Free Space Isolators that deliver outstanding performance. Our isolators cover a power range from 300mW to 200W. They offer high isolation (33dB for single-stage series and 50dB for dual-stage series), low insertion loss, excellent environmental stability, and minimal thermal lens effects. The inclusion of a beam expander enables customers to adjust system magnification while maintaining high-quality beam output.

Key Features:

• High isolation: Achieve 33dB (single-stage series) or 50dB (dual-stage series) isolation
• Low insertion loss: Maintain optimal signal transmission efficiency
• Excellent environmental stability: Suitable for demanding operating conditions
• Low thermal lens effect: Minimize distortion and maintain beam quality
• Beam expander included: Adjust system magnification with high-quality beam output

Applications:

• Fabrication of fiber lasers: Ensure stability and performance in fiber laser systems
• Optical fiber sensors: Enhance the reliability and sensitivity of fiber optic sensing setups
• Laser gauges: Improve precision and accuracy in laser measurement applications
