Product Description
With compatibility across 780nm to 1080nm (covering 780/980/1030/1064nm), it eliminates the need for multiple wavelength-specific isolators in multi-band systems. Its 58×28×26mm package (optimized for high-power heat dissipation) and flexible customization (fiber type, power rating, connectors) make it ideal for high-demand industrial and laboratory setups.
Product Features
Broad Wavelength Coverage: Supports 780-1080nm (780/980/1030/1064nm).
20W High-Power Tolerance: Handles up to 20W continuous-wave power + 10kW peak pulses (5ns), catering to high-power MOPA fiber lasers and amplifiers.
Ultra-Low Insertion Loss: 0.8dB typical loss (max 1.0dB) — 30% lower than standard high-power isolators, minimizing signal waste in high-gain systems.
TGG-Type Stability: TGG crystal core ensures consistent isolation (30dB typical) and low polarization-dependent loss (0.15dB max) across the full wavelength range.
Optimized Heat Dissipation: 58×28×26mm package design supports efficient heat management for long-term high-power operation (a critical feature for 20W systems).
Flexible Customization: Options for average power (0.3W-20W), fiber type (PM/SM), and connectors (FC/UPC/APC, SC) to fit specific system requirements.
Product Applications
Pump Fiber Amplifiers: Protects high-gain amplifiers from reverse pump light interference.
MOPA Fiber Lasers: Ensures stable output for high-power pulsed laser systems.
Fiber Lasers: Shields laser diodes from back-reflection-induced damage in industrial processing setups.
Optical Test Instruments: Maintains measurement accuracy in high-power component validation labs.
