Product Description
Product Features
100W High-Power Tolerance: Supports up to 100W continuous-wave power + 10kW peak pulses (5ns), catering to high-power MOPA fiber lasers and amplifiers (a capability rarely offered by entry-level free-space isolators).
Ultra-Low Insertion Loss: 0.15dB typical loss (max 0.3dB) — 70% lower than standard free-space isolators, minimizing signal attenuation in high-gain systems.
Broad Wavelength Coverage: 780-1080nm range (780/980/1030/1064nm) eliminates the need for multiple single-wavelength isolators in multi-band setups.
Dual Aperture Options: 5.2mm (≤2.0mm beam) and 5.5mm (≤5.0mm beam) apertures to fit diverse free-space beam sizes.
High Extinction Ratio: 95% typical extinction ratio ensures near-complete suppression of reverse light interference.
Robust TGG Stability: TGG crystal core maintains consistent performance across +10~+50°C operating temperatures, suitable for industrial environments.
Product Applications
Pump Fiber Amplifiers: Protects high-gain amplifiers from reverse pump light in free-space coupling setups.
MOPA Fiber Lasers: Ensures stable output for high-power pulsed laser systems used in industrial processing.
Fiber Lasers: Shields laser diodes from back-reflection damage in free-space beam delivery systems.
Optical Test Instruments: Maintains measurement accuracy in high-power component validation labs.
