Short answer: Choose an isolator by wavelength, power and polarization: low-power PM or SM in-line isolators for seeds and sensing, TGG high-power in-line isolators (10–100 W listed) for fiber laser outputs, and free-space TGG isolators where the beam leaves the fiber. KernsOptic lists models from 532 nm to 2050 nm and 300 mW to 100 W CW; see the selection guide.

ENGINEERING NOTES

Configuration details

Key choices to confirm before selecting a model or requesting engineering review.

What wavelength and power range do KernsOptic optical isolators cover?

Listed models cover 532 nm to 2050 nm and from 300 mW up to 100 W CW, in PM, polarization-insensitive, multimode and free-space versions.

When do I need a PM optical isolator?

When the light is linearly polarized and the downstream system depends on that polarization, such as PM fiber amplifiers, frequency conversion or coherent sensing. Otherwise a polarization-insensitive isolator is usually used.

Can you build a non-standard isolator?

Yes, custom wavelength, fiber, power and package requests are reviewed by engineering before quotation. Prototypes are paid; typical lead time is 4–10 weeks.
