1064nm High Power Collimated Beam Output Isolator
High Power Collimated Beam Output Isolator is one of the fiber in and free space out isolators. 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 application, such as Laser marking and engraving, Laser cutting and etching of metal surfaces with high reflectance such as Aluminum, Copper, Gold or Silver, Micro Machining and Trimming. These high-power handling isolators have a pigtail fiber input and a collimated-beam output. A wide range of output beam diameters are standard (3 mm ~ 10 mm).
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.
