Description
The GKER Photonics 1064 nm Polarization Insensitive Isolator (GK-PSSI & GK-PDSI Series) is designed to block unwanted back reflections and feedback in high-power laser systems while maintaining reliable performance across all polarization states. With its advanced optical design and compact packaging, the isolator provides high isolation (up to 55 dB), low insertion loss, and high return loss, ensuring optimal signal integrity.
The device supports both continuous wave (CW) and pulsed laser sources and can handle peak powers up to 10 kW for nanosecond pulses and continuous wave powers up to 300 mW. This makes it an ideal choice for high-performance applications such as fiber lasers, Raman amplifiers, and advanced photonic systems.
Built with HI 1060 fiber and robust environmental stability, the isolator operates reliably across a wide temperature range. Available in single and dual stage variants with multiple grades and customizable connector and fiber options, this isolator offers flexibility and precision performance for demanding optical networks.
