High Power Polarization Insensitive Isolator (GK-HI Series)

The 980 nm High Power Polarization Insensitive Isolator (HPII) is indeed a specialized optical component designed for high-performance applications in fiber lasers and instrumentation. Here's a detailed overview based on the provided search results:

Low Insertion Loss: This isolator typically has an insertion loss of around 0.6 dB at 23°C, with a maximum insertion loss not exceeding 1.0 dB at the same temperature.

High Isolation: It offers a typical peak isolation of 32 dB and a minimum isolation of at least 25 dB at 23°C across all polarization states.

High Power Handling: The isolator can handle power ranging from 1W to 20W, with some models capable of handling up to 10kW peak power for pulsed applications.

High Return Loss: It provides a minimum return loss of 50 dB for both input and output.

Excellent Environmental Stability and Reliability: The isolator is designed to operate within a wide temperature range of -5°C to +75°C for working temperature and -40°C to +85°C for storage temperature, ensuring stable performance in various environmental conditions.

Polarization Insensitivity: With a maximum polarization-dependent loss (PDL) of 0.1 dB at 23°C, the isolator ensures consistent performance regardless of the polarization state of the input light.

These characteristics make the 980 nm High Power Polarization Insensitive Isolator an ideal choice for applications where high power, reliability, and stable performance are critical, such as in fiber lasers, fiber amplifiers, fiber communication systems, and fiber sensors .
