Key Features of Fiber-Free Space Isolators
- Efficiently blocks reverse transmission beams to enhance optical system stability.
- Available in expanded and non-expanded beam isolator designs tailored to diverse optical systems.
- High isolation levels: >33 dB for single-stage and >50 dB for dual-stage configurations.
- Low insertion loss, superior beam quality, and excellent environmental stability.
- Customizable options for various power ranges, fiber types, and housing configurations.
General Description
Fiber-Free Space Isolators are designed to prevent reverse transmission beams, ensuring the stability and precision of fiber laser systems. POC offers two primary types: non-expanded and expanded beam isolators. The non-expanded beam isolator includes birefringent crystals, Faraday rotators, and wave plates, enabling effective reverse beam isolation in optical systems. In contrast, the expanded beam isolator integrates a beam expander to produce high-quality, focused beams with minimized divergence angles.
These isolators feature high isolation levels (up to 50 dB for dual-stage designs), low thermal lens effects, and exceptional environmental performance. POC uses advanced crystal fabrication techniques and premium optical components to ensure consistent performance. The devices are customizable, offering a range of options to meet specific application requirements, including fiber type, wavelength, and housing configurations.
Applications
- Fabrication of Fiber Lasers
Fiber-free space isolators are essential in fiber laser systems for preventing back reflections, maintaining system stability, and improving overall efficiency in industrial and scientific applications. - Optical Fiber Sensors
These isolators are used in high-precision optical fiber sensing systems, ensuring minimal noise and enhanced measurement accuracy by blocking reverse transmission beams. - Laser Gauging
In laser measurement systems, the isolators ensure precision and stability, critical for gauging applications in advanced manufacturing and research.
