Technical Datasheet Note & Cooling Requirements
Conduction or water cooling is strictly required for 100W CW continuous operation. The mounting baseplate temperature must be maintained at ≤ 30°C using water cooling with a recommended flow rate of 1.0–1.5 L/min (thermal impedance < 0.2 K/W via OFHC copper heatsink mount). Fiber leads available in 10/125, 20/130, 25/250, 30/250 PM or non-PM DCF. Custom configurations confirmed during Engineering Review.
Configuration and ordering notes

Selected for multi-kilowatt laser systems, high-power fiber amplifiers, and laser cutting engines. Engineering review covers average power rating (50W or 100W), operating wavelength, and fiber core/cladding diameter during configuration review.

Selection Guidance: Review thermal dissipation, damage thresholds and cooling options in our High Power Optical Isolator Guide ↗ or compare operating bands in the 1064nm and 1550nm Optical Isolator Selection.

Key Applications

High-power fiber lasers; Fiber laser welding & cutting; High-power amplifier protection; Medical & scientific laser systems.
