1064nm High Power Optical Isolator

Product Overview-1064nm High Power Optical Isolator

Box Optronics supplies the 1064nm High Power Optical Isolator, a high-performance passive optical component designed to protect laser sources, seed lasers, and optical amplifiers from harmful optical feedback caused by reflected and backscattered light. Based on the Faraday rotation effect, this isolator enables non-reciprocal light transmission, allowing light to pass in the forward direction with low loss while blocking reverse-direction light with high isolation.

Featuring typical insertion loss, high isolation, and high extinction ratio, this 1064nm isolator is optimized for high-power fiber laser and amplifier systems. It supports average power handling up to 10W and peak power up to 10kW for ns pulse operation, making it suitable for demanding industrial and scientific applications.

Product Details-1064nm High Power Optical Isolator

What is an Optical Isolator?

An optical isolator, also known as a Faraday isolator, is a passive two-port optical device that allows preferential transmission in one direction while providing high isolation in the reverse direction. It is an essential component in laser and fiber optic systems toprotect laser sources and optical amplifiers from optical feedback caused by reflected and backscattered light.

Optical isolators are based on the Faraday effect, which utilizes a magneto-optic material that rotates the polarization of light passing through it when subjected to a magnetic field.Combined with polarizers, this polarization rotation enables forward optical transmission and high isolation of reverse-propagating light.

Operation Notes and Handling-1064nm High Power Optical Isolator

ESD Protection

While optical isolators are passive devices, proper handling is required to maintain performance and reliability.

• Work on a clean, dust-free surface

• Avoid touching the fiber end-faces directly

• Keep dust caps on connectors when not in use

• Use proper ESD protection during handling and installation

• Handle with care to avoid damaging fiber pigtails

Fiber Handling

• Avoid excessive bending of the fiber

• Do not pull or twist the fiber pigtails

• Clean fiber connectors before connection using proper cleaning tools

• Always use dust caps when the connector is not in use

• Inspect fiber end-face for damage before use

• Do not exceed maximum tensile load (5N)

Power Handling Considerations

• Ensure input power does not exceed the rated maximum

• Use proper power monitoring to avoid overload

• Allow for proper heat dissipation at high power levels

• Mount on a heat sink for high power continuous operation

Installation and Mounting

• Mount the isolator securely using the 4 mounting holes

• Ensure proper alignment to minimize additional loss

• Allow sufficient space for fiber bending radius

• Operate within the specified temperature range for reliability

• Avoid mechanical stress on the fiber pigtails

• Ensure proper port orientation for correct signal direction

• Verify forward/reverse direction before installation
