Features

Minimize Feedback into Optical Systems

Wavelength Ranges from 770 to 2010 nm

Polarization Independent and Dependent Versions

Available With or Without Connectors

Minimum 1 m Length of Fiber per side of each Isolator

Fiber isolators protect laser sources from back reflections and signals that can cause instabilities and damage to fiber coupled laser sources. An isolator is an optical device that allows light propagating in the forward direction to be transmitted, while absorbing or displacing light propagating in the reverse direction (see schematic above). Fiber isolators are available in both polarization-dependent and polarization-independent models throughout the 770 to 2010 nm wavelength range. High power fiber isolators are built using a specialized fiber end face process to increase power handling capabilities. A minimum of 1 m of fiber is included on both sides of each fiber isolator.

IOK-1064-LMA25-CRED

The IOK-1064-LMA25 is a fiber-to-free space isolator for high-power applications in the 1064 nm range. Utilizing our experience in high-power fiber coupling, this isolator has been fabricated to withstand CW laser powers up to 50 W. This isolator has the added benefit that a red aiming laser with transmission in the 633 to 690 nm range can be coupled into the LMA25 fiber prior to entering the isolator. This aiming feature is extremely useful when working with a free-space IR beam. Mounting holes on the output facet allow components such as beam expanders to be attached. Without a beam expander, a Ø1 mm collimated beam will exit the isolator centered on the body with a divergence that is less than 1.5 mrad.
