Frequently Asked Questions

What is a 1064nm High Power Collimated Free-space Beam Output Isolator?
A 1064nm High Power Collimated Free-space Beam Output Isolator is an optical device designed to allow light to pass in one direction while blocking it in the reverse direction. It features a fiber pigtail input and a collimated free-space beam output, making it ideal for high-power fiber lasers and amplifiers operating at 1064nm. This isolator helps protect sensitive laser components from back reflections and feedback, ensuring stable and reliable operation.
What are the key features of DK Photonics' 1064nm High Power Free-space Isolator?
Key features include low insertion loss, high power handling (up to 50W CW or kW-level peak), high isolation (up to 35dB), excellent temperature stability, high reliability, and customizable fiber types and output beam diameters (0.5mm to 10mm). Both polarization-maintaining (PM) and non-PM versions are available, with options for single or double cladding fibers.
What applications are suitable for this high power free-space isolator?
This isolator is ideal for use in fiber lasers, fiber amplifiers, instrumentation, test and measurement setups, and laboratory research involving fiber amplifiers. Its high power handling and reliable isolation make it suitable for both industrial and research environments where back-reflection protection is critical.
How do I select the right configuration for my application?
To select the right configuration, specify the central wavelength (980nm, 1030nm, 1064nm, 1080nm, or custom), required optical power (CW or pulsed, up to 50W), fiber type (core/clad/NA), fiber jacket and length, and output beam diameter. DK Photonics offers customization for fiber pigtails, power handling, and other specifications to meet your unique requirements.
What is the difference between PM and non-PM types, and which should I choose?
PM (Polarization Maintaining) isolators preserve the polarization state of the input light, which is essential for applications requiring stable polarization, such as certain laser systems. Non-PM isolators do not maintain polarization and are suitable for general applications. Choose PM if your system is polarization-sensitive; otherwise, non-PM may suffice.
What are the typical isolation and insertion loss values for this isolator?
Typical peak isolation values range from 30dB to 35dB, with a minimum in-band isolation of 25dB to 30dB at 25°C. The minimum transmission is 90%, and the return loss is at least 45dB. Insertion loss is kept low to ensure high efficiency in your optical system.
