Project Description

1064nm High Power In-line Optical Isolator

The 1064nm high power isolator series includes in-line type, beam expanded isolator, fiber in and free space out isolator and free space isolator etc. They’re characterized with low insertion loss, high isolation, high power handling, high return loss, excellent environmental stability and reliability. Optical Isolators are optical devices that allow light to be transmitted in one direction only. They are most often used to prevent any reflected light from entering the source, thus preventing any feedback problems; it has been widely used in fiber laser system.

For wavelength of 1064nm, PM and non-PM types are available, fiber can be customized, with power conditions of CW or Pulse and Power Handling of 5W, 10W, 20W, 30W, 50W can be customized.

If you do not see a standard isolator that meets your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed.

  1. Above specification are for device without connector, and may change without notice.
  2. IL is 0.3 dB higher and RL is 5 dB lower, ER is 2dB lower (PM type) for each connector added.
  3. The pass optical power is 2 W only for connector added, the connector is only used for performance testing at low power, higher power requires splicing fibers.
  4. Type B: Both axis working, Type F: Fast axis blocked, the default is Type B if without request (Only for PM type)
  5. If there is pulse application, please be sure to inform us of pulse energy and peak power.

Order information

P/N: HPPII (HPPMI-B/F)-①-②-③-④-⑤-⑥ (HPPMI-B/F: High Power Polarization Maintaining Isolator)

When you inquire, please provide the correct P/N number according to our ordering information, and attach the appropriate description would be better. If need any connector, we do not recommend choosing a 250μm bare fiber pigtail. For high power applications, we recommend direct splicing without connectors.
